Detailed Description
Piecewise polynomial curve object. This class provides a trivial implementation of piecewise polynomial curves. More useful spline/B-spline implementations might follow in the future. The PPCurves are of the form
![\[\sum_{i=0}^{d} a_i^{(k)} (x - x_0^{(k)})^i\]](../../form_32_dark.png)
