Vender ModelingToolkit.jl with diffeqpy?

[ChrisRackauckas]

It seems like it would be a good front end for diffeqpy which would allow users to easily build Julia functions and get the full speed. I would need help finding out how to vender it so it just shows up, but from there it should be quite straightforward. The macros couldn't be used, but the constructor form would work, and we can just add constructors that allow strings and convert internally to symbols so that it works natively from Python.

@tkf I'm having some trouble using MTK from Python. Do you have any suggestions for things like symbols and arithmetic overloads?

from julia.api import Julia
jl = Julia(compiled_modules=False)
from julia import ModelingToolkit
from jl import Main

x = jl.eval("ModelingToolkit.Variable(:x)")
y = jl.eval("ModelingToolkit.Variable(:y)")
z = jl.eval("Symbol(\"x\")")

ModelingToolkit.Variable(z) # error
x+y # error
