/*
* This function uses the vcs_MultiPhaseEquil interface to the
* vcs solver.
* The function uses the element abundance vector that is
* currently consistent with the composition within the phases
* themselves. Two other thermodynamic quantities, determined by the
* XY string, are held constant during the equilibration.
*
* @param s The object to set to an equilibrium state
*
* @param XY An integer specifying the two properties to be held
* constant.
*
* @param estimateEquil integer indicating whether the solver
* should estimate its own initial condition.
* If 0, the initial mole fraction vector
* in the %ThermoPhase object is used as the
* initial condition.
* If 1, the initial mole fraction vector
* is used if the element abundances are
* satisfied.
* if -1, the initial mole fraction vector
* is thrown out, and an estimate is
* formulated.
*
* @param printLvl Determines the amount of printing that
* gets sent to stdout from the vcs package
* (Note, you may have to compile with debug
* flags to get some printing).
*
* @param maxsteps The maximum number of steps to take to find
* the solution.
*
* @param maxiter For the MultiPhaseEquil solver only, this is
* the maximum number of outer temperature or
* pressure iterations to take when T and/or P is
* not held fixed.
*
* @param loglevel Controls amount of diagnostic output. loglevel
* = 0 suppresses diagnostics, and increasingly-verbose
* messages are written as loglevel increases. The
* messages are written to a file in HTML format for viewing
* in a web browser. @see HTML_logs
*
