This should be fixed now.

I added member functions to MeshFunction for broadcast and receive which 
 were wrappers for MPIMeshCommunicator::broadcast(..)/receive(..), 
analogous to Mesh::broadcast()/receive(). The problem is that 
MeshFunction is a templated class.

To keep a consistent interface, I see two options:

a) Create specialisations of MeshFunction::broadcast()/receive(); or

b) Remove the Mesh::broadcast()/receive() wrapper functions and call 
MPIMeshComminicator::broadcast(..)/receive(..) directly.
