Unit Testing

Use within PFLOTRAN

Initially we should focus on developing unit tests for "mathematical" functions, i.e. functions or subroutines that take simple input parameters and return a value or vector of values. The best functions are those that don't require setting up complex data structures. Examples are interpolation functions, equations of state, constitutive relationships.
