??????: Fix error of TKernal and TMath compilation.

Error occured if using c++20 standard with new oneTBB 2021.5.0. The error was: Error C2672 'tbb::v1::parallel_for_each': no matching overloaded function found TKernel could be 'void tbb::detail::d2::parallel_for_each(Iterator,Iterator,const Body &)' TKernel 'tbb::detail::d2::parallel_for_each': the associated constraints are not satisfied TKernel Note, that if we use c++14 or c++17, all ok, error does not occures. To solve the problem, i have to modify `UniversalIterator` class: `value_type` instead `UniversalIterator` converted to `IteratorInterface*` `pointer` = `reference` = `value_type` Method `DownCast` moved into `FunctorInterface` abstract class. argument `UniversalIterator& item` of the unary fuctions converted to `IteratorInterface*`. The proposed solution solved the compilation error.
moving to intel oneTBB 2021*

+ Build 3rd-parties {#build_upgrade_building_3rdparty}
+==============================================
+@tableofcontents
+
+On Windows, the easiest way to install third-party libraries is to download archive with pre-built binaries from https://dev.opencascade.org/resources/download/3rd-party-components.
+On Linux and macOS, it is recommended to use the version installed in the system natively.
+
+@section dev_guides__building_3rdparty_win_1 Windows
+
+This section presents guidelines for building third-party products used by Open CASCADE Technology (OCCT) and samples on Windows platform.
+It is assumed that you are already familiar with MS Visual Studio / Visual C++.
+
+You need to use the same version of MS Visual Studio for building all third-party products and OCCT itself, in order to receive a consistent set of runtime binaries.
+
+It is recommended to create a separate new folder on your workstation, where you will unpack the downloaded archives of the third-party products, and where you will build these products (for example, `c:/occ3rdparty`).
+Further in this document, this folder is referred to as `3rdparty`.
+
+@subsection dev_guides__building_3rdparty_win_2 Tcl/Tk
+
+Tcl/Tk is required for DRAW test harness.
+
+**Installation from sources: Tcl**
+
+Download the necessary archive from https://www.tcl.tk/software/tcltk/download.html and unpack it.
+  
+1. In the `win` sub-directory, edit file `buildall.vc.bat`:
+
+   * Edit the line `"call ... vcvars32.bat"` to have correct path to the version of Visual Studio to be used for building, for instance:
+
+         call "%VS80COMNTOOLS%\vsvars32.bat"
+
+     If you are building 64-bit version, set environment accordingly, e.g.:
+
+         call "%VS80COMNTOOLS%\..\..\VC\vcvarsall.bat" amd64
+
+   * Define variable `INSTALLDIR` pointing to directory where Tcl/Tk will be installed, e.g.:
+
+         set INSTALLDIR=D:\OCCT\3rdparty\tcltk-86-32
+
+   * Add option `install` to the first command line calling `nmake`:
+
+         nmake -nologo -f makefile.vc release htmlhelp install %1
+
+   * Remove second call to `nmake` (building statically linked executable)
+
+2. Edit file `rules.vc` replacing line
+
+       SUFX	    = tsgx
+
+   by
+
+       SUFX	    = sgx
+
+   This is to avoid extra prefix 't' in the library name, which is not recognized by default by OCCT build tools.
+
+3. By default, Tcl uses dynamic version of run-time library (MSVCRT), which must be installed on the system where Tcl will be used.
+   You may wish to link Tcl library with static version of run-time to avoid this dependency.
+   For that:
+
+   * Edit file `makefile.vc` replacing strings `"crt = -MD"` by `"crt = -MT"`
+
+   * Edit source file `tclMain.c` (located in folder `generic`) commenting out forward declaration of function `isatty()`.
+
+4. In the command prompt, run `buildall.vc.bat`<br>
+   You might need to run this script twice to have `tclsh` executable installed; check subfolder `bin` of specified installation path to verify this.
+
+5. For convenience of use, we recommend making a copy of `tclsh` executable created in subfolder `bin` of `INSTALLDIR` and named with Tcl version number suffix, as `tclsh.exe` (with no suffix)
+
+       > cd D:\OCCT\3rdparty\tcltk-86-32\bin
+       > cp tclsh86.exe tclsh.exe
+
+**Installation from sources: Tk**
+  
+Download the necessary archive from https://www.tcl.tk/software/tcltk/download.html and unpack it.
+Apply the same steps as described for building Tcl above, with the same `INSTALLDIR`.
+Note that Tk produces its own executable, called `wish`.
+
+You might need to edit default value of `TCLDIR` variable defined in `buildall.vc.bat` (should be not necessary if you unpack both Tcl and Tk sources in the same folder).
+
+@subsection dev_guides__building_3rdparty_win_2_2 FreeType
+
+FreeType is required for text display in a 3D viewer.
+You can download its sources from https://freetype.org/
+
+1. Unpack the downloaded archive of FreeType product into the `3rdparty` folder.
+   As a result, you will get a folder named, for example, `3rdparty/freetype-2.4.10`.
+   Further in this document, this folder is referred to as `freetype`.
+
+2. Open the solution file `freetype/builds/win32/vc20xx/freetype.sln` in Visual Studio.
+   Here `vc20xx` stands for your version of Visual Studio.
+
+3. Select the configuration to build: either `Debug` or `Release`.
+
+4. Build the `freetype` project.<br>
+   As a result, you will get a `freetype` import library (`.lib`) in the `freetype/obj/win32/vc20xx` folder.
+
+5. If you build FreeType for a 64 bit platform, select in the main menu `Build - Configuration Manager`
+   and add `x64` platform to the solution configuration by copying the settings from `Win32` platform:
+
+   @figure{/build/build_3rdparty/images/3rdparty_image001.png}
+
+   Update the value of the Output File for `x64` configuration:
+
+   @figure{/build/build_3rdparty/images/3rdparty_image003.png}
+
+   Build the `freetype` project.<br>
+   As a result, you will obtain a 64 bit import library (`.lib`) file in the `freetype/x64/vc20xx` folder.
+   To build FreeType as a dynamic library (`.dll`) follow steps 6, 7 and 8 of this procedure.
+
+6. Open menu Project-> Properties-> Configuration  Properties-> General and change option `Configuration Type` to `Dynamic Library (.dll)`.
+7. Edit file `freetype/include/freetype/config/ftoption.h`:<br>
+   in line 255, uncomment the definition of macro `FT_EXPORT` and change it as follows:
+
+       #define FT_EXPORT(x)   __declspec(dllexport) x
+
+8. Build the `freetype` project.<br>
+   As a result, you will obtain the files of the import library (`.lib`) and the dynamic library (`.dll`) in folders `freetype/objs/release` or `freetype/objs/debug`.
+   If you build for a 64 bit platform, follow step 5 of the procedure.
+
+   To facilitate the use of FreeType libraries in OCCT with minimal adjustment of build procedures,
+   it is recommended to copy the include files and libraries of FreeType into a separate folder, named according to the pattern `freetype-compiler-bitness-building mode`, where:
+   * `compiler` is `vc8` or `vc9` or `vc10` or `vc11`;
+   * `bitness`  is `32` or `64`;
+   * `building mode` is `opt` (for `Release`) or `deb` (for `Debug`).
+
+   The `include` subfolder should be copied as is, while libraries should be renamed to `freetype.lib` and `freetype.dll` (suffixes removed) and placed to subdirectories `lib` and `bin`, respectively.
+   If the `Debug` configuration is built, the Debug libraries should be put into subdirectories `libd` and `bind`.

+   If you use a Visual Studio version higher than VC++ 2008, apply conversion of the workspace.
+   Such conversion should be suggested automatically by Visual Studio.
+
+3. Select a configuration to build.
+   - Choose `Release` if you are building Release binaries.
+   - Choose `Debug` if you are building Debug binaries.
+
+   *Note:*
+
+   If you want to build a debug version of FreeImage binaries then you need to rename the following files in FreeImage projects:
+
+   Project -> Properties -> Configuration Properties -> Linker -> General -> Output File
+
+       FreeImage*d*.dll  to FreeImage.dll
+
+   Project -> Properties -> Configuration Properties -> Linker -> Debugging-> Generate Program Database File
+
+       FreeImage*d*.pdb  to FreeImage.pdb
+
+   Project -> Properties -> Configuration Properties -> Linker -> Advanced-Import Library

+
+   Project -> Properties -> Configuration Properties -> Build Events -> Post -> Build Event -> Command Line
+
+       FreeImage*d*.dll     to FreeImage.dll
+       FreeImage*d*.lib     to FreeImage.lib
+
+   Additionally, rename in project FreeImagePlus
+
+   Project -> Properties -> Configuration  Properties -> Linker -> Input -> Additional Dependencies
+
+       from FreeImage*d*.lib to FreeImage.lib
+
+4. Select a platform to build.
+   - Choose `Win32` if you are building for a 32 bit platform.
+   - Choose `x64` if you are building for a 64 bit platform.
+
+5. Start the building process.<br>
+   As a result, you should have the library files of FreeImage product in `freeimage/Dist` folder (`FreeImage.dll` and `FreeImage.lib`).
+

+VTK Integration Services component provides adaptation functionality for visualization of OCCT topological shapes by means of VTK library.
+
+1. Download the necessary archive from https://www.vtk.org/VTK/resources/software.html and unpack it into `3rdparty` folder.<br>
+   As a result, you will get a folder named, for example, `3rdparty/VTK-6.1.0`.
+   Further in this document, this folder is referred to as `VTK`.
+
+2. Use CMake to generate VS projects for building the library:
+   - Start CMake-GUI and select `VTK` folder as source path, and the folder of your choice for VS project and intermediate build data.
+   - Click **Configure**.
+   - Select the VS version to be used from the ones you have installed (we recommend using VS 2015) and the architecture (32 or 64-bit).
