description:
Added class NewVariable and Label, planning to replace existing Variable.

Unlike Variable, NewVariable is not a Terminal, meaning the subexpression
is an operand and can be handled in algorithms like other general operands.

It is also not a Counted, but has a second operand of the type Label
which is both a Terminal and Counted.

description:
Implemented lhs and rhs, works for basic "a = u*v*dx + f*v*ds",
needs verification and testing for more complicated stuff
and probably some more operators handled.

description:
Some work on derivative function.

Disabled _metadata in Form, this breaks the
immutable property which is very important.
Need a very good reason to re-enable it!
