    This adds a multElementwise() method to the DGFunction class and extends
    the associated FunctionMultElementwiseTest. For this to work smoothly the
    commit also performs the following two updates on the DGFunction:
    
    - it adds an assign() version for a constant value
    - it changes the interface of the other assign() method for functions
      to use a vector of reference wrappers instead of a vector of pointers
      so that it is consistent with assign in the other function classes,
      like P1Function etc.
