### f162 Create projected cur_conic

Description
Creates a rational cubic parametric segmented curve that interpolates two or more positions and tangents. Any positions and tangents may be specified but will automatically be projected to the XY-plane of the active coordinate system before the curve is created. cur_conic does not care about the length of tangents, only the direction. For every segment a Midpoint or P-value must also be specified. A Midpoint is just any intermediate position while a P-value is a scalar float that controls the "fullness" of the segment. P-values should be in the range 0.0 < P < 0.85.

If tangents are chosen in such a way that they intersect and form a nice triangle with the segment chord as baseline then the resulting segment becomes a classical plane conic segment (quadric rational). If the tangents are chosen in such a way that inflexion or twist is forced the resulting segment becomes a cubic rational generalized (3D-) conic.
