reactants to be interpreted as moles per liter of WATER or
moles per liter of ROCK:
UNITS
-equilibrium_phases ROCK

-surface WATER
-solid_solution WATER
-kinetics WATER
-gas_phase WATER
By default, the number of moles of solid reactants are
interpreted as per liter of water. Using the ROCK option,
PHAST interprets the number of moles of solid
reactants obtained from the initial PHREEQC calculation
as per liter of rock.
Note that an initial PHREEQC calculation is made at the
beginning of a PHAST run. During this calculation all
reaction calculations interpret the concentration of solid
reactants as simply moles. (When a solution is reacted with
the solids, the solution contains a mass of water, which is
usually 1 kg, but not necessarily.) It is only when initial
conditions are subsequently distributed in the PHAST calculation
that solid reactants are scaled. If the units are WATER, t
here is no scaling and the number of moles of solids is the
number of moles per liter of water. If the units are ROCK,
the number of moles of a solid reactant is multiplied by
(1-phi)/phi, where phi is the porosity in the cell receiving
the initial condition, to arrive at the number of moles of
solid reactant per liter of water.
The addition of the ROCK option is motivated by the possibility
of a domain with a distribution of porosities. In this case,
the number of moles of solid reactants per liter of water--
the units used by PHAST--also vary spatially. By using the
ROCK option, a constant rock composition can be defined and
the factor (1-phi)/phi is used to scale the number of moles
of solid reactant to obtain the number of moles per liter
of water in each cell.

Phreeqcpp class methods.
Still compiles on Debug and Release, but problem with
phrq_malloc in cvdense and cvode.

Moved some methods for .h to source files to avoid need for includes.
Debug and Release compile.
Still need to get class version working.

fraction. Now adds the two fractions.
This created a bug with rivers when mixing with the same solution. The mass fraction
was calculated incorrectly because only the second part of the solution was used (solution, frac 2).
