Added support for patchwise evaluation of surface tension to the
phaseSystem.
Filled out submodel interfaces to make it easier to add new models.
Made submodel parameters user modifiable in LemmertChawla model.
Added Kocamustafaogullari-Ishii nucleation site density and departure
frequency models and renamed the existing KocamustafaogullariIshii
departure diameter model to KocamustafaogullariIshiiDepartureDiameter.
Relaxation is now also applied to the quenching heat flux to be
consistent with the evaporative heat flux.
Improved iteration loop diagnostics. The maximum wall temperature change
on the last iteration is printed out if the maximum number of iterations
(10) is reached.
