description:
Applying renumber_indices in FormData constructor,
hopefully this makes the signature more consistent.
We might need some more processing to make it truly canonical.

Bugfix in renumber_indices.

description:
Removed dependencies.py, graph tools are
more suitable than split_by_dependencies.

Renamed basisfunction -> basis_function everywhere except filename.

I recommend deleting your old installation and build/ before reinstalling now.

description:
Implemented MultiFunction class, using a mechanism similar to
the one in Transformer to dispatch calls to different functions
based on the type of their first argument. Unlike Transformer,
not intended for recursive calls on the expression tree
but single calls. Example:

class MyFunction(MultiFunction):
    def __init__(self):
        MultiFunction.__init__(self)
    def expr(self, o):
        print "Got an expr of type %s" % type(o)
        return 1
    def function(self, o):
        print "Got a function!"
        return 2

# Guess what these will print:
f = MyFunction()
one = f(something_not_a_function)
two = f(some_function)


Using this for PartialDerivativeComputer which will
be used for reverse mode AD in the future, and for
figuring out dependencies based on type in graph
partitioning.
