0024157: Parallelization of assembly part of BO

Patch 06

I.1. class Bnd_Box2d
- method:
inline Standard_Real Bnd_Box2d::SquareExtent() const
has been added.
Purpose : The method returns the squared diagonal of the bounding box.

I.3. class BOPCol_BoxBndTree
has been added.
Purpose : The class is the instantiation of the algorithm of unbalanced binary tree
of overlapped bounding boxes 3D.

I.4. class BOPCol_Box2DBndTree
has been added.
Purpose : The class is the instantiation of the algorithm of unbalanced binary tree
of overlapped bounding boxes 2D.

I.5. class BOPAlgo_Algo
- method:
void BOPAlgo_Algo::SetRunParallel(const Standard_Boolean theFlag)
has been added.
Purpose: Set the flag of parallel processing
     if <theFlag> is true  the parallel processing is switched on
     if <theFlag> is false the parallel processing is switched off

- method:
Standard_Boolean BOPAlgo_Algo::RunParallel()const
has been added
Purpose: Returns the flag of parallel processing

II.1. class BOPAlgo_Builder
- method:
void BOPAlgo_Builder::SetRunParallel(const Standard_Boolean theFlag)
has been removed due to I.5.

- method:
Standard_Boolean BOPAlgo_Builder::RunParallel()const
has been removed due to I.5

II.2. class BOPDS_BoxBndTree
has been removed due to I.3

II.3. classes
BOPDS_Iterator,
BOPDS_IteratorSI,
BOPDS_SubIterator
BOPAlgo_PaveFiller,
BOPAlgo_Builder
the calls to BOPDS_BoxBndTree have been changed to
the calls to BOPCol_BoxBndTree
due to I.3

II.4. class BOPAlgo_BuilderFace
- method:
void BOPAlgo_BuilderFace::PerformLoops()
the changes that provide parallel run the  WireSplitter algorithm have been done.

- method:
void BOPAlgo_BuilderFace::PerformAreas()
the classification the grows and holes has been done using
the algorithm of unbalanced binary tree of overlapped bounding boxes

II.5. class BOPAlgo_WireSplitter
- method:
void BOPAlgo_WireSplitter::SplitBlock(const TopoDS_Face& myFace,
			          BOPTools_ConnexityBlock& aCB)
the method is transferred to the static, the signature of the method have been changed

- method:
void BOPAlgo_WireSplitter::MakeWires()
the changes to provide parallel run the SplitBlock algorithm have been done
