MonadMulti classes

class Monad m => MonadMultiReader a m where

All methods must be defined.

The idea is: Any monad stack is instance of MonadMultiReader a, iff the stack contains a MultiReaderT x with a element of x.

In contrast to MonadMultiReader, MonadMultiGet is defined for State too, so it corresponds to read-access of any kind.

Note however that for MultiRWS, only the values from the state part can be accessed via MonadMultiGet, due to limitations of the design of MultiRWS and of the type system. This is issue is resolved in the MultiGST type.
