GDE Prototype Code v0.2.

New feature:

Industrial exposure is now treated per administrative unit or in terms of a 30-arcsec grid, depending on how it is defined in the input aggregated model (e.g. SERA for Europe). This new feature includes two new modules: GDE_TOOLS_create_industrial_cells.py and SERA_creating_industrial_cells.py. 30-arcsec cells get treated as administrative units of level "99".
