v0.13.0

Full Strike and Fatality risk maps given areas. Currently the parameters for the wind etc, are not patched through to UI.

CUDA implementation now used preferentially to CPU bound impl for risk map generation. This relies on a supported Nvidia GPU and working install of CUDA toolkit. This is checked for by the existence of a CUDA_HOME environment variable pointing to the install.

Command Line Interface created and documented, however wheels need to built from source due to local dependencies not being possible to pre package.
