Implemented single and two-phase boiling/condensation heat transfer correlations for internal pipe flow.. One correlation model (SmoothCorrelations) may replace liquid, two-phase and vapor correlations and provide smooth phase transitions, in addition to further geometry inputs that are neeeded. So far the correlations are from the Modelica.Dissipation library, but can easily be extended..

Only change in Thermocycle library structure is the extending class used for heat transfer models, that now needs to be PartialTwoPhaseMedium instead of PartialMedium.

Have a look and feel free to modify as much as wanted..
