vptp_ptr	Pointer to the Variable pressure ThermoPhase object This object must have already been malloced.
spindex	Species index within the phase
inputFile	XML file containing the description of the phase
id	Optional parameter identifying the name of the phase. If none is given, the first XML phase element will be used.
