- Add fig 1 from manuscript
- re-arrange sections (features, installation, documentation, examples)
- move this to somewhere in the docs; remove from readme
Note that the directional methods (forward, backward) find models with the smallest step size (in terms of number of estimated parameters). For example, given the forward method and a predecessor model with 2 estimated parameters, if there are no models with 3 estimated parameters, but some models with 4 estimated parameters, then the search may return candidate models with 4 estimated parameters.
