Feature request: a method for the objects obtained from lmer, glmer of package lme4

[iagogv3]

I have tried autoplot with ggfortify loaded for a model output of the function lmer of the package lme4. I have tried also ggfortify:::autoplot.lm applied to the model and did not work any of both options.
It would be great if you could add a method for the class merMod (lmerMod, glmerMod).

Thanks!
