2014-07-12	Docx Reader: Add a compatibility layer for Except.	Jesse Rosenthal	1	-0/+27
	mtl switched from ErrorT to ExceptT, but we're not sure which mtl we'll be dealing with. This should make errors work with both. The main difference (beside the name of the module and the monad transformer) is that Except doesn't require an instance of an Error Typeclass. So we define that for compatability. When we switch to a later mtl, using Control.Monad.Exception, we can just erase the instance declaration, and all should work fine.
