Adds ttplot to generate colorful terminal plots if you lack windowing access; Adds util_DerivedQty to compute nontrivial functions of the primitive variables.
Working radiating hydrodynamic shock experiment; Modifies free radiation function to cutoff by temperature and not Einternal.
Revises boundary conditions implementation for greater speed; Adds cubic solver that magnetized radiating flow solver will need; Fixes frame loader utility to avoid double load of first rank's data; Finally finishes derived quantity calculator.
