description:
Added unused sketch of FormTransformation framework,
considering using this to postphone computation of form
transformations like the derivative until the compilation stage.

Enabled and mixed elasticity form and updated it with the right operators.
Implemented correct latex rendering of second order list tensor.

description:
Removed is_linear from Expr and algebra classes,
its meaning wasn't well defined and it had only
a few small and buggy implementations.

Wrote down some brainstorming on index renumbering,
which we'll need for canonical representation of
forms independent of previous form definitions
since we all have this global counter stuff.
Otherwise the form compiler caches will break
very easily.
