Speed Calculator

[BrianG]

Arct1k, are you trying to find work for me to do?

Fluid calc: Good idea. Didn't change it too much from the original aside from visuals. Might add that feature.

Temp Calc: I think C and F are good enough. Who (besides you apparently) uses Kelvin when measuring temps?

Two-speed mesh calc: Why does it matter what pitch it is? I know the code is technically using Mod1 to get the gear diameters, but the ratio is what matters. The only reason Mod1 is currently used is because I was going to add shaft-to-shaft distance, but decided not to, and didn't feel like changing the mesh code again.
