Detailed Description

Tests FitBasis python binding for FourierBasis, Chebyshev1Basis, Chebyshev2Basis, and Chebyshev2.

It tests FitBasis by fitting to a ground-truth function that can be represented exactly in
the basis, then checking that the regression (fit result) matches the function.  For the
Chebyshev bases, the line y=x is used to generate the data while for Fourier, 0.7*cos(x) is
used.
