Draft: provide access to optimization functions
- renamed squeeze.py to lib. with the purpose of housing more general functions
- added a function
optimize_PRM_transmissivity
which exposes the PRM transmissivity optimization provided byifo_power
- changes
computeFCParams
so that the optimal parameters are returned instead of directly modifying the ifo struct
This relies on the ifo_power
function which is undergoing changes in !138
closes #73
