"""Script for running a hypothetical inundation scenario for Gold Coast,
QLD, Australia.

Source data such as elevation and boundary data is assumed to be available in
directories specified by project.py
The output sww file is stored in project.outputtimedir 

The scenario is defined by a triangular mesh created from project.polygon,
the elevation data and a tsunami wave generated by s submarine mass failure.
