|---|---|---|
| p | float * | array of points (np*dim floats) |
| np | int | number of points in array |

This class implements a Bezier curve of any dimension (1D, 2D, 3D, etc...).
The curve and tangent can be evaluated at any point, and the curve can be adaptively subdivided until the curve error is less then a maximum error factor.
