bugfix: #2025 getCurveBP (and others) segfault

This method is now unsupported.  The original intent appears to
return the first BPoint of an Ipo curve.  However, BPoint Ipo curves
are not implemented and the first point therefore never existed.

The segfault was from an unchecked input parameter.

Calling this method now always throws a NotImplemented exception.
