Mathy Models in HARK

Input/Output:

• A serialized model representation for describing models (and exporting) them.
  • Probably dolang
• For a given model, it should be possible to print or export a human-readable text version of model with its equations, as in the BufferStock notebook.

Architecture:

• A Python object that represents the equations, which can be fed into more generic model solution/simulation architecture.
  • E.g transition equations, functions to calculate expectations over distributions, reward functions, ...
