Function hofpT1 computes h(p,T) in region 1.  
Function handsofpT1 computes (s,h)=f(p,T) in region 1, needed for two-phase properties.  
Function hofps1 computes h(p,s) in region 1.  
Function hofpT2 computes h(p,T) in region 2.  
Function handsofpT2 computes (s,h)=f(p,T) in region 2, needed for two-phase properties.  
Function hofps2 computes h(p,s) in region 2.  
Function hofdT3 computes h(d,T) in region 3.  
Function hofpsdt3 computes h(p,s,dguess,Tguess) in region 3, where dguess and Tguess are initial guess  
          values for the density and temperature consistent with p and s.  
Function hofps4 computes h(p,s) in region 4.  
Function hofpT5 computes h(p,T) in region 5.  
Function water_hisentropic computes h(p,s,phase) in all regions.  
          The phase input is needed due to discontinuous derivatives at the phase boundary.  
Function water_hisentropic_dyn computes h(p,s,dguess,Tguess,phase) in all regions.  
          The phase input is needed due to discontinuous derivatives at the phase boundary. Tguess and dguess are initial guess  
          values for the density and temperature consistent with p and s. This function should be preferred in  
          dynamic simulations where good guesses are often available.
