IAPWS95 1.1.0

Second Issue

This is the second issue of this package, with a new function to compute the water vapor pressure according to the Wagner and Pruß equation (1993). Every function of the R Code was revised to eliminate the automatic echo; now the return should be assigned to a local variable.
