Identified Graphing Errata

I have identified graphing errata that happens at certain stages.  Occasionally, the graph will reset and revert back to the Kelvin temperature scale.  If the temperature units have been changed prior to that event, the graph will draw the correct temperature but at the wrong unit scale. 

At this point, this seems to be the graphing library crashing and resetting.  It is too early to tell if that's the case for certain, though.

Fixed Temperature Process Indicators

The temperature process indicators were not calculating correctly when temperature units were changed.  This has been corrected so the process indicators remain consisted through temperature conversions.

Pressure indicators were also corrected.

Final Water-State Zone Completed

I implemented the Antoine formula to calculate saturated vapor pressure at temperatures between the LGS Triple point and the critical point.
