Base64 encoder which claims to be much faster than the iharder encoder that we currently use. Might consider using it, but it would need a little tweaking to provide an alternative "URL-safe" alphabet mode like the iharder library does.

This is the particular form of the Hermite spline that I have been using for my trajectories, though I have just been dealing with two points at a time.

In the code that I have been writing for the last year or two I specify a trajectory by giving the values and time derivitives of two control points. Thanks to my co-worker Ramin for pointing out that this technique is called a Hermite spline.
