GeochemicalModelInterrogator

This sets up a very simple MOOSE simulation, with zero time steps, no "usual" solution process, no "usual" output, etc. The only thing the simulation does is add a GeochemicalModelInterrogator userobject, which outputs balanced reactions and equilibrium constants, activity ratios, equilibrium temperature, etc (and then MOOSE exits). See the GeochemicalModelInterrogator userobject for more discussion.

An example is

# Outputs equilibrium reactions fo Clinoptil-Ca for various different basis species, along with log10(K)
