%description
Fit data to an ellipse, hyperbola, or parabola. Bootstrapping is available
when needed. The conic curve can be rotated through an arbitrary angle and
the fit will still succeed. Helper functions are provided to convert
generator coefficients from one style to another, generate test data sets,
rotate conic section parameters, and so on. References include Nikolai
