warnings and errors

[tvall]

Should we save all warnings and errors for the individual models, or just let them print to the screen? Definitely we should save errors b/c otherwise if you run 500 you have to track down which one broke.

probably add something like "errors = true" to log errors

probably add something like "errors = true" to log errors

and still have them print to the console regardless?
