'''
Andrew Till
Summer 2014
Materials specification subroutines.
Uses nuclide_data python module by Joshua Hykes that has been modified to use python module uncertainties version 2. The data is based on NIST data.
Dependencies: numpy, uncertainties (ver 2), nuclide_data (https://github.com/jhykes/nuclide-data; updated to work with ver 2 of uncertainties), directories (dirDict), Readgroupr (to read potential xs and define some mt2name dicts), iapws (https://github.com/jjgomera/iapws/; for water densities)
