Title: Fixed bug from paper

While writing the paper on the derivatives stuff, i discovered a small inconsistency between the different differentiators in when I call calc_derivatives. This fixes that inconsistency by moving the call to calc_derivatives out of the driver and into the differentiators. This cleans up the interface on the driver side, to hopefully make it less confusing.
