0029523: Problem with BRepOffsetAPI_MakeEvolved

Browse Source 
The capabilities of the class BRepOffsetAPI_MakeEvolved have been extended with involving alternate algorithm of resolving the loops in the piped shape. The new option theIsVolume is added for that in the constructor.

New class BRepFill_AdvancedEvolved has been created in order to provide new OCCT-algorithm combining BRepFill_PipeShell and BOPAlgo_MakerVolume.

A change in BOPAlgo_PaveFiller.cxx has been made in order to solve a specific problem of Boolean operation.

The interface of DRAW-command "evolved" has been updated to add the new option. DRAW-command "evolvedsolid" has been deleted. Now it is replaced with DRAW-command "evolved" with the option "-solid".

Testgrid "evolved" has been created.
