We now allow src/build_function to take NamedTuples as a datastructure for building a function

[raphaelchinchilla]

This is a simple addition to build_function that dramatically increases its versatility. Here is a small example:

@variables x[1:2] y[1:2]
op=x+y
z=(x=x,y=y)
code_fun=build_function(op,z)[2]

code_fun is:

:(function (ˍ₋arg1,)
      begin
          (broadcast)(+, ˍ₋arg1.x, ˍ₋arg1.y)
      end
  end)

This is useful because the built function uses the "." to access the elements of the input, for instance _-arg1.x. So we can pass to the built function any datastructure where the elements are accessed using ".", which obviously includes NamedTuples, but also structs and ComponentArrays.

Can you add a test?

[raphaelchinchilla]

Yes. Do they need to be as thorough as the ones in /test/build_function_arrayofarray ? Or should I just include some additional tests?

[raphaelchinchilla]

Hi all, I have had some busy days and did not have time yet to include the tests.

Please correct me if I am wrong, but the build error is not related to my PR, right?

[raphaelchinchilla]

@ChrisRackauckas I just included the tests that you asked me to.

They are an exact copy of the test for build_function_arrayofarray.jl but the numeric inputs as well as the symbolic inputs are NamedTuples. I verified that without the change in build_function in this PR, these tests all fail.

[ChrisRackauckas]

this file isn't in runtests.jl so it's not tested.

[raphaelchinchilla]

Sorry, I forgot about that. Just did it.
