Hmm, the template class pushes new messages onto the message stack? I  
think
that really is the responsibility of the controller. And if so, the  
pop method
should be located in the same class.

Anyway, if it really makes sense, we could extract the whole flash  
messaging
mechanism into its own class acting as a service. But currently for me  
it
seems unnecessary.
