akaftasev d03c08988c 0021264: Modeling Algorithms - Progress indicator for Boolean operations 
Update BOP commands to use progress indicator
Deleted wrong usage of progress indicator from bop operations
Added UserBreak() method to break execution boolean operation if progress indicator is used
Added method AnalyzeProgress() to calculate steps of progress indicator
Introduce BOPAlgo_ParallelAlgo which has myRange as a field to be used in parallel vector.
Provide suitable way of keeping the progress steps of operations.
Give meaningful names to progress scopes.
Propagate progress indicator into deeper methods of BOA.
Add progress indicator to BOPAlgo_BuilderFace and BOPAlgo_WireSplitter, BOPAlgo_BuilderSolid and BOPAlgo_ShellSplitter
