Detailed Description

Class for defining a model independent partial wave component where the amplitudes are parameterised in terms of real and imaginary parts.

This model uses splines to produce a partial wave from the values of the real and imaginary parts of the amplitude at a series of points in the phase space. The values at each point can be floated in the fit.
