+	PhreeqcRM: Fixed a bug when the diffuse-layer was lost in a PhreeqcRM calculation
+	with a Runge-Kutta integration and the rate went to zero. The error produced charge 
+	imbalance because the surface transformed to a no-EDL surface; charge accumulated
+	on the surface was balance by a charge imbalance in the solution.
