NCollection_BaseCollection class, relevant header files, and macro DEFINE_BASECOLLECTION removed.
Hence methods Assign() from other compatible (via inheritance of BaseCollection) collections are not available any more, as well as base Iterator class.
All methods of Iterator classes are made non-virtual, allowing their inline expansion for better performance.
OCCT-specific operators new and delete added to collection classes and removed from iterator classes.
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
