0024157: Parallelization of Assembly part of BO

The Build (Assembly) Part of BO consists of several sub-parts:
1. Building Vertices
2. Building Edges
3. Building Faces
4. Building Solids
5. Building Container Shapes (Wires, Shells, Compsolids, Compounds)

Among the parts above
3.Building Faces
and
4.Building Solids
are the most time-consuming and thus should be parallelized first.

The parallelization process can be divided on three phases:
1. Parallelization Building Faces
2. Parallelization Building Solids
3. Parallelization the rest parts

The phase 1 : Parallelization Building Faces consists of three parts:
1.1. Building Split Faces
1.2. Building Same Domain Faces
1.3. Building Faces with Internal Shapes
The branch deals with the phase 1. chapter 1.1. Building Split Faces
