Hello!

I am automating the building of a ufl form. Something like:

  # create list_of_forms
  my_form = Zero()*dx
  for form in list_of_forms:
      my_form += form

For the for loop to work I need to initate my_form to Zero()*dx, because it 
need to be a form. 

Any other ideas of how this can be done? If this is the only way can 
someone(TM) expose 'Zero' to the main ufl namespace? 

It resides in:

  constantvalue.py
