0028782: Shape sewing behavior not consistent for the same CAD file

Browse Source 
Get rid of iterations on maps with shape key by replacing simple maps with indexed maps. So iteration is done on integer key.

The map containers have been updated to insert into them type definitions of key and value.

The new methods RemoveKey() and RemoveFromIndex() have been added to indexed [data] map to be able to remove an arbitrary key from the map.

All the code in OCCT has been updated where RemoveLast() and Substitute() methods were used to remove a key from indexed [data] map.
