0028189: Result of Boolean operation is non-manifold wire

1. The result of Boolean operation on the arguments of collection type, containers WIRE/SHELL/COMPSOLID, is now also a collection.
The result of Boolean operation on arguments of non-collection types is now a compound containing the splits of arguments directly, without its enclosure into containers.
Thus, if there were no containers, such as WIRE/SHELL/COMPSOLID, in the input arguments there will be no such containers in the result of BOP.

2. The containers of type WIRE included into result should now also (as the SHELLs) have coherent orientation of its sub-shapes.
For that the new method has been implemented (BOPTools_AlgoTools::OrientEdgesOnWire(TopoDS_Shape&)) which reorients edges of the given shape for correct ordering.

3. The duplicating containers, i.e. containers with the contents completely included in other containers, are now avoided in the result of BOP.

4. Documentation has been updated.

5. New test cases for the issue.

6. Adjusting test cases to current behavior.

* The result of the operation Cut is defined for arguments *S1* and *S2* that have values of dimensions *Dim(S2)* that should not be less than *Dim(S1)*. The dimension of the result is equal to *Dim(S1)*. The result of the operation *Cut12* is not defined for other cases. For example, it is impossible to cut an edge from a solid, because a solid without an edge is not defined.
* The result of the operation *Cut12* for arguments *S1* and *S2* contains the parts of argument *S1* that have state **OUT** relative to the opposite argument *S2*.
* The result of the operation *Cut21* for arguments *S1* and *S2* contains the parts of argument *S2* that have state **OUT** relative to the opposite argument *S1*.
* For the arguments of collection type (WIRE, SHELL, COMPSOLID) the type will be passed in the result. For example, the result of Common operation between Shell and Wire will be a compound containing Wire.
* For the arguments of collection type (WIRE, SHELL, COMPSOLID) containing overlapping parts the overlapping parts passed into result will be repeated for each container from the input shapes containing such parts. The containers completely included in other containers will be avoided in the result.
* For the arguments of collection type (WIRE, SHELL, COMPSOLID) the containers included into result will have the same orientation as the original containers from arguments. In case of duplication its orientation will be defined by the orientation of the first container in arguments. Each container included into result will have coherent orientation of its sub-shapes.
* The result of the operation Fuse for the arguments of collection type (WIRE, SHELL) will consist of the shapes of the same collection type. The overlapping parts (EDGES/FACES) will be shared among containers, but duplicating containers will be avoided in the result. For example, the result of Fuse operation between two fully coinciding wires will be one wire, but the result of Fuse operation between two partially coinciding wires will be two wires sharing coinciding edges.
* The result of the operation Fuse for the arguments of type COMPSOLID will consist of the compound containing fused solids.
* The result of the operation Common for the arguments of collection type (WIRE, SHELL, COMPSOLID) will consist of the unique containers containing the overlapping parts. For example, the result of Common operation between two fully overlapping wires will be one wire containing all splits of edges. The number of wires in the result of Common operation between two partially overlapping wires will be equal to the number of connexity blocks of overlapping edges.
