Comment by TNTricker:
I don't know if this has been brought up but what about the ability to
trace and evaluate the functions on the plot? or some support to render
intervals on an axis in multiples of pi,e,i, or any other arbitrary value.

gc stands for Generalized Coordinate in mechanics these are typically
always functions of time.

It isn't too pressing for PyDy, I just ran into it when creating some
tests that would ensure PyDy gave the same output as Autolev. In
Autolev, if you express a UnitVector from one reference in the
coordinates of another reference frame that is 3 or more simple
rotations away, when you convert

I just finished reading this paper. It seems pretty reasonable, and
not to difficult to implement. Does anybody know of any other papers
on this subject that might offer alternative methods that would be
worth looking at? If there was some sort of gold standard paper on
the subject, that might
