When you call crv.getTangentsToPoint( pt ), it will return a list of numbers. Each number is a curve parameter value marking the location on the curve of a tangent solution.

Curve parameters will be inside the parametric domain of the curve, between crv.domainMin at the start of the curve, ranging up to crv.domainMax at the end of the curve.
