0025232: Functionality to create solids from set of shapes

Browse Source 
Purpose:
The algorithm is to build solids from set of shapes.
It uses the BOPAlgo_Builder algorithm to intersect the given shapes and build the images
of faces (if needed) and BOPAlgo_BuilderSolid algorithm to build the solids.
Steps of the algorithm:
1. Collect all faces: intersect the shapes if necessary and collect  the images of faces,
   otherwise just collect the faces to the <myFaces> list.
   All faces on this step added twice, with orientation FORWARD and REVERSED;
2. Create bounding box covering all the faces from <myFaces> and create solid box from corner points
   of that bounding box (myBBox, mySBox). Add faces from that box to <myFaces>;
3. Build solids using faces from <myFaces> using BOPAlgo_BuilderSolid algorithm;
4. Treat the result: Eliminate solid containig faces from <mySBox>;
5. Fill internal shapes: add internal vertices and edges into created solids;
6. Prepare the history.

Fix for regression.
class BOPAlgo_BuilderSolid:
The tolerance value used in BRepClass3d_SolidClassifier has been increased.

Test cases for issue CR25232

Small correction to eliminate the warning.

class MakerVolume from BOPAlgo
inherits Builder from BOPAlgo
---Purpose:
-- The algorithm is to build solids from set of shapes.
-- It uses the BOPAlgo_Builder algorithm to intersect the given shapes
-- and build the images of faces (if needed) and BOPAlgo_BuilderSolid
-- algorithm to build the solids.
--
-- Steps of the algorithm:
-- 1. Collect all faces: intersect the shapes if necessary and collect
-- the images of faces, otherwise just collect the faces to the
-- <myFaces> list;
-- All faces on this step added twice, with orientation FORWARD
-- and REVERSED;
--
-- 2. Create bounding box covering all the faces from <myFaces> and
-- create solid box from corner points of that bounding box
-- (myBBox, mySBox). Add faces from that box to <myFaces>;
--
-- 3. Build solids from <myFaces> using BOPAlgo_BuilderSolid algorithm;
--
-- 4. Treat the result: Eliminate solid containig faces from <mySBox>;
--
-- 5. Fill internal shapes: add internal vertices and edges into
-- created solids;
--
-- 6. Prepare the history.
--
-- Fields:
-- <myIntersect> - boolean flag. It defines whether intersect shapes
-- from <myArguments> (if set to TRUE) or not (FALSE).
-- The default value is TRUE. By setting it to FALSE
-- the user should guarantee that shapes in <myArguments>
-- do not interfere with each other, otherwise the result
-- is unpredictable.
--
-- <myBBox> - bounding box, covering all faces from <myFaces>.
--
-- <mySBox> - Solid box created from the corner points of <myBBox>.
--
-- <myFaces> - the list is to keep the "final" faces, that will be
-- given to the BOPAlgo_BuilderSolid algorithm.
-- If the shapes have been interfered it should contain
-- the images of the source shapes, otherwise its just
-- the original faces.
-- It also contains the faces from <mySBox>.
--
--
-- Fields inherited from BOPAlgo_Builder:
--
-- <myArguments> - list of the source shapes. The source shapes can have
-- any type, but each shape must not be self-interfered.
--
-- <myShape> - Result shape:
-- - empty compound - if no solids were created;
-- - solid - if created only one solid;
-- - compound of solids - if created more than one solid.
--
--
-- Fields inherited from BOPAlgo_Algo:
--
-- <myRunParallel> - Defines whether the parallel processing is
-- switched on or not.
-- <myErrorStatus> - Error status of the operation:
-- 0 - operation successful;
-- 100 - no shapes to process;
-- 102 - BOPAlgo_PaveFiller algorithm has failed;
-- 103 - BOPAlgo_BuilderSolid algorithm has failed.
--
-- Example:
--
-- BOPAlgo_MakerVolume aMV;
-- //
-- aMV.SetArguments(aLS); //source shapes
-- aMV.SetRunParallel(bRunParallel); //parallel or single mode
-- aMV.SetIntersect(bIntersect); //intersect or not the shapes from <aLS>
-- //
-- aMV.Perform(); //perform the operation
-- if (aMV.ErrorStatus()) { //check error status
-- return;
-- }
-- //
-- const TopoDS_Shape& aResult = aMV.Shape(); //result of the operation
--
