  1. Move fitting into 'check' and use in 'validate'. 

    Make checkAstrometry and checkPhotometry run fits
of expected error behavior from astrometric and photometric.

  1. Re-structure fit structs to be self-documenting 

    checkAstrometry and checkPhotometry now return a struct
that clearly labels its fit parameters and model name.
