0024639: Parallelization FillDS part of BO

Edge/Edge Interferences

Changes:
1. class BOPAlgo_PaveFiller
  - method:
void BOPAlgo_PaveFiller::PerformEE()
the chages provides the parallel computations of
Edge/Edge interferences.

   - auxiliary classes:
    BOPAlgo_EdgeEdge
    BOPAlgo_EdgeEdgeFunctor
    BOPAlgo_EdgeEdgeCnt
have been added.
The classes are auxiliary classes to provide the parallel computations
of Edge/Edge interferences.

2. class BOPTest
-method:
void BOPTest::PartitionCommands(Draw_Interpretor& theCommands)
- static function:
Standard_Integer bfillds(Draw_Interpretor& di,
                         Standard_Integer n,
                         const char** a)
The syntax of the command "bfillds" has been changed.
> bfillds [-s -t]
options:
-s - launch the algorithm in sequential mode
-t - display CPU time
