"""
Generates ascii grids of nominated areas -
Input: sww file from run_perth.py
       boundaries for grids from project.py
Outputs: ascii grids of specified variables
Stored in the 'outputs_dir' folder for respective .sww file

Note:
If producing a grid for the enitre extent cellsize should be greater than 30m
If producing grids for inundation area resolution should be greater than mesh (ie ~22m)
