Model documentation

[hdrake]

Should add documentation using Documenter.jl which is mostly made up of documentation markdown files but also also nicely publishes the source code w/ source code docstrings.

I've got a proof-of-concept of this working at https://github.com/hdrake/MARGO.jl/tree/documenting, following the step-by-step Documenter.jl guide, but haven't yet deployed it as a standalone github page.

Planning on adding the bare minimum of documentation to #28 before releasing v0.1.0.

• Landing page
• Installation instructions
• A basic example
• Guide for contributors
• Description of model parameters (by submodule)
• Optimization process
• How to use the diagnostic functions

[hdrake]

Added some auto-generating docs in #33 with Literate.jl, which turns a basic .jl julia script fill with special comment formatting into a beautiful .md document with code cells and ouputs (including figures!).

Need to be updated to be consistent with the published version of the model!

Edit: As of v0.3.2, the documentation is once again consistent with the model.

The plotting functions still need to be listed 📊
