Initial release

A stand-alone flight-track simulator code that can be embedded into a weather/climate model workflow. This code outputs high resolution data on a number of pre-defined flight tracks by interpolating modelled dynamical, chemical, and aerosol diagnostics from the model grid to the flight times/locations. This data is then written to a CF-compliant, netcdf file that can be efficiently stored, due to its small size, and more easily compared to flight observations.
