mbedinger/USAH-outputs: USAH-outputs (v2.0)

This is the fifth release of USAH-outputs (v2.0).

This included USAH outputs from a paper soon to be in review in the journal Civil Engineering and Environmental Systems, held in the subfolder USAH-outputs/2021-xx - Civil Engineering and Environmental Systems. The baseline USAH used in this work is version 2.0. This is then modified to model urban impacts of three hypothetical hazard scenarios (drought, flood, and pandemic) on a generic UK city.
