Most of the plots allowing for faceting, but add faceting to those that do not. In particular:
covCat
Do we want to keep R^2 and p-values in these plots? There's not going to real estate and I'm not sure it'd be clear what we're indicating the p-values on. I think we should just drop them if you facet.
covCont
Same comment regarding R^2 and p-values
Do we want to allow stratification in the GOF plots? I think that'd probably be a bit too crowded.
