Create Decapode from equation

[fivegrant]

The user will likely create and edit Decapodes at the equation level. Therefore, having a way for a user to declare equations that are then compiled to work with Decapodes would be a big value add.

Is this just writing the decapodes code itself? E.g.

Advection = @decapode begin
  C::Form0
  ϕ::Form1
  V::Form1
  ϕ == ∧₀₁(C,V)
end

So I think if the notebook let's you write Julia and the sysimage has the libraries loaded this should work out of the box, right?

If the user were to "load in" another decapode (e.g. #21) then they could compose this Advection decapode they craft in the notebook with, say, a Diffusion one they load in from Terarium.

Does that make sense?

@brandomr the idea here is that the DSL wouldn't be used and plain unicode/latex/mathml/something else could be used to declare the equation. The conversion to a Decapode should happen under the hood
