Geometry_Engine: Add PointAtParameter for ellipse

[IsakNaslundBh]

Issues addressed by this PR

Closes #2936

Add implementation of PointAtParameter for ellipse.

Implementation added does not correspond to normalised length along the curve but rather normalised angle along the curve, which for the case of an ellipse imo is a more sensical way of dealing with it.

Also adding Descriptions and null checking for all methods
