Closes #49

Draft started in notebooks

Questions:

  • Shear transformation convert and deconvert from (g1, g2) parametrization, OK?
  • How to add measurement noise? convert and deconvert again?
  • What prior to use on the magnitude on shear?

We discussed and it was ok to just get the posterior of |g| by taking the g1, g2 samples and sqrt-summing them in square. Done in #58
