0026560: BRepBndLib build too large bounding box in Z direction for planar spline edge.

Browse Source 
Poles bounding box for curve added for bezier and bspline curves.
Method Poles() for Bezier curve added.

Test case for issue CR26560

Function to compute subshape max tolerance has been added.
Fixed bounding box expanding at Face/Face step of boolean operation.
Test cases are updated to the new behavior.
