[PolyChord] use ppf for pc_prior instead of prior bounds #104

  1. change pc_prior to make use of scipy's .ppf 

    * Use scipy's .ppf (inverse cdf) that comes with all major 1d distributions for
  PolyChord's prior function, which needs to map the unit hypercube to the
  physical parameters. Previously the prior bounds were used to effectively turn
  any 1d prior into a uniform prior. That's fine for the evidence, but causes
  problems e.g. for the relative entropy from prior to posterior.
* Pass the loglikelihood to PolyChord instead of logposterior+logvolume.
