Coding - Add clang-format configuration #246

Browse Source 
New clang-format configuration added to determinate code style.
The default version is 16.
Extend CMake to copy config file to build root.
Method/function separator deprecation:
  In case if function/method has declaration in header,
    definition must not have related comment.
    Only //==== [100 chars] ==== is allowed as a not connected
    separator.
  In case if function/method has  NOT declaration in header,
    definition must have related comment in doxygen style:
    // Descriptions
    // @param
    // @return
    Or just function/method separator:
    //==== [100 chars] ====
  All old separators with no description must be replaced to
    //==== [100 chars] ====
