…softening instead of hardening-only)
Use time (lookback time) as independent variable instead of binary separation to allow for binary 'softening' (i.e. da/dt > 0). Integrate each binary, one at a time, from initial conditions until either coalescence or redshift zero. Evolution arrays thus are no longer always the same size. Currently evolution arrays are 1D objects, flattened for all binaries, and the appropriate indices are stored (Evolution._last_index). This *seems* to be working (first full implementation). Lots more changes will be needed to allow for interpolation, universe-realization, etc. Its also extremely slow. There are numerous obvious problematic places, e.g. interpolation of CBD_Torques and Dynamical Friction halo relations. Cython could also speed things up a lot, but the issue will be external function calls. Really, this should be a second Evolution class, so that both implementations are preserved for the moment... I'll add the old one back in later.
