Tutorial Ch 2: Create a box-model that runs MICM for one timestep

[mattldawson]

Create a box model (for a single well-mixed air mass) that allows solving a single time step for one grid cell with a MICM solver

Acceptance Criteria

• Tutorial describes how to create a host application that can run the MICM solver and get results for one time step and one grid cell

Ideas

• Follow the logic use in this test
• Just hard-code the initial conditions
• Output results to stdout
