class Context from IntTools
---Purpose:
--- The class is to provide direct access
--- to the frequently using objects like
--- IntTools_FClass2d,
--- GeomAPI_ProjectPointOnSurf, etc.
--- The instance of the class allows to avoid repeated
--- computations by mapping internal objects in the
-- instance.
