Add support for surrogate production over a reduced basis
Currently heron only supports reproducing time-domain waveforms in the time domain, which can be slow.
It's time to develop models which use alternative basis projections to make (much) faster surrogates.
- Add a general reduced basis class
Add abscissa (linear) interpolation to allow compatibility with
- Add tests for the basic class
- Add tests for the sample BBH model
- Document the sample BBH model
