Calculations in Adaptor2d_OffsetCurve are unified with similar calculations in Geom2d_OffsetCurve using methods extracted from Geom2dEvaluator_OffsetCurve to Geom2dEvaluator.cxx
BRepFill_OffsetWire.cxx, Geom2dGcc_Circ2d2TanRadGeo.cxx, Geom2dGcc_Circ2dTanOnRadGeo.cxx, MAT2d_Circuit.cxx are modified to satisfy changing offset direction.
Macro NO_CXX_EXCEPTION was removed from code.
Method Raise() was replaced by explicit throw statement.
Method Standard_Failure::Caught() was replaced by normal C++mechanism of exception transfer.
Method Standard_Failure::Caught() is deprecated now.
Eliminated empty constructors.
Updated samples.
Eliminate empty method ChangeValue from NCollection_Map class.
Removed not operable methods from NCollection classes.
1. Implemented evaluators for 2D and 3D offset curves
2. Removed obsolete namespace CSLib_Offset
Update of UDLIST (adding no-cdl-pack Geom2dEvaluator)
Update TKG2d/CMakeLists.txt after rebase
Correction compilation in debug mode
