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