2Script for building boundary to run tsunami inundation scenario for Perth,
3WA, Australia.  The boundary is based on the National Hazard Map.
4
5Input: order_filename from project.py
6       event_number needs to be reflected in the project file
7Output: creates a sts file and csv files stored in project.boundaries_dir_event.
8The run_perth.py is reliant on the output of this script.
