PyBaMM - Printing Formatted Equations

PyBaMM offers a way to compare new models by implementing models as expression trees that can be specified independently of the user's preference. This allows the model to be defined independently of the user's choice of parameters, spatial discretization, numerical methods and so on, which are plugged in during model processing. This project aims to use LaTeX to render the expression tree into a human-readable format using SymPy and also generate a file of the model equations to visualize the equations easily.
