3. Tested on OS4.

2. Allow minimum enthalpy input of -80 BTU/lb for both single-state and mixed-air calc modes.

3. Allow user to specify low- or high-accuracy calculation mode for purposes of speeding up some of the calcs.

4. More accurate calculations for a number of input parameter combinations.

5. Added 3 additional pairs of input parameter combinations so the total is now 23.
