Soichiro Morisaki requested to merge soichiro/bilby:qprior into master Oct 26, 2020

This MR is to implement the prior of mass ratio for the case where the uniform prior on component masses is applied while mass ratio is sampled.

The analytic expressions of its PDF and CDF are given in https://git.ligo.org/soichiro.morisaki/utilities/-/blob/master/mcq_sampling_bilby/mcqprior.pdf .

It has been tested in https://git.ligo.org/soichiro.morisaki/utilities/-/blob/master/mcq_sampling_bilby/CheckNewAnalyticPrior.ipynb .
