Add optional shearing of input objects #26

Closed sweverett closed 6 years ago

sweverett commented 6 years ago

Most of this is already handled by GalSim - but since we deal with 'modified' GalSim yaml files, we'll have to update a bit of the checks done in config._load_input_catalogs() to make sure we don't mess up the input indexing for add_gs_injection(). This isn't an issue for adding a constant shear but there are a few edge cases for PowerSpectrumShear, for example.

We should also add the relevant ellipticity-ellipticity (difference) correlation function to the standard plots (#19). There is a prototype plotting routine there but it needs some updating.
