0029481: Implementation of the Feature Removal algorithm

Browse Source 
Implementation of the 3D model De-featuring algorithm intended for the removal of the unwanted parts (or features) from the model consisting of solids. The features can be the holes, protrusions, gaps, chamfers, fillets etc.
The algorithm removes all possible requested features from the shape and builds the new shape as a result. The input model is not modified.

On the API level the algorithm is implemented in the class *BRepAlgoAPI_Defeaturing*. The actual features removal is performed by the low-level algorithm *BOPAlgo_RemoveFeatures*.

Documentation of the new classes.
Implementation of the DRAW commands for working with new algorithm.
Test cases for the new functionality.

Changes in other algorithms used by De-featuring algorithm:
- Provide history support for the solids in *ShapeUpgrade_UnifySameDomain* algorithm;
- Implementation of the mechanism to merge History of any Algorithm with standard history methods such as IsDeleted(), Modified() and Generated() into *BRepTools_History*.
