description:
Updated demo files. Some were still missing 'forms' or using wrong form names.
Added (temporarily) demo/HyperElasticityWorkaround.ufl, which compiles with FFC.
SFC uses 33 s to compile this while FFC spends 1:07 m.

description:
Implement tuple notation, now in algorithms/tuplenotation.py.
Form compilers should use ufl.algorithms.as_form to convert from
tuple (or Form) to Form. I tried placing as_form in form.py but
this did not work due to some recursive imports. It's now in
tuplenotation.py. Here's how it's done in FFC:

    forms = []
    elements = []
    for object in objects:
        if isinstance(object, FiniteElementBase):
            elements.append(object)
        elif not object is None:
            forms.append(as_form(object))
