Now that we can generate equations of motion from a Lagrangian (should work in theory for Hamiltonians too but I haven't tried), it'd be really slick if we could pipe that solution into a differential equation solver and get a numerical solution.

@PerezHz works on TaylorIntergration.jl so if he wants to get that running, that'd be great. I'd also like DifferentialEquations.jl support at some p

As a convenience, we should provide meta tensor implementations of the following:
__add__, __radd__, __sub__, __rsub__, __mul__, __rmul__, __div__, __rdiv__, __truediv__, __rtruediv__, __floordiv__, __rfloordiv__, __mod__, __rmod__, __lt__, __le__, __gt__, __ge__, __and__, __rand__, __or__, __ror__, __xor__, __rxor__, __getitem__, __pow__, `__rp

Scalar and vector functions should only be created using element_of, which returns objects of type ScalarTestFunction and VectorTestFunction. Therefore there is no need for the old classes ScalarField and VectorField, which should be removed from the library.

Additionally, since the space to which scalar/vector functions belong is either a ScalarFunctionSpace or a `VectorFunctionSpa
