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.
