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

\[\sum_{i=0}^{d} a_i^{(k)} (x - x_0^{(k)})^i\]

, where $k$ is the index of the interval and $d$ is the overall degree of the PPCurve. Note that there is no warranty that the defined curve is continuously differentiable or even continuous.
