description:
Moved MultiIndex back to base.py, inheriting Terminal.
It needs to be part of the UFLObject, otherwise the
general iteration procedures break on Indexed.
Made PartialDerivative use MultiIndex just like
Indexed, such that PD.operands() returns objects
from the UFLObject hierarchy. This also means
we can support foo.dx(i,j) for second and higher
order derivatives.

Improved ufl2latex such that it handles complete forms
with multiple integrals, and indexed expressions.
Added its output to ufl-analyse, try it on the forms under demo/!

description:
Bugfix in index handling with ellipsis.
Bugfix in Dot.__repr__.

Implemented expand_compound(expression), which expands
Dot, Inner, Outer, Transpose, Div, Grad, [Curl, Rot not implemented]
into indexed expressions. Not verified, needs unit tests.

We also need better unit tests for indexing,
and tests and cleanup of PartialDerivative.
