Add possibility of construction of the Optimal Oriented Bounding Box from set of points (the case of shape with triangulation). The interface of the BRepBndLib::AddOBB method is not changed, but the option <theIsOptimal> now controls also the construction of the OBB from Set of points. The slightly modified DiTo algorithm will be used, checking all possible axes created by the extreme points. The performance of the construction of the Optimal OBB is lower but the quality is usually much higher (can't be worse by definition). Test cases for the issue.
