[Feature Request] Change shooter radius to diameter in flywheel calculator

[mdurrani808]

Most teams and mechanical design calculators deal with the diameter of the shooter wheel when doing accepting numbers for calculations rather than the radius. ReCalc using radius can cause confusion for students because they are used to seeing / talking about diameter, not radius.

I see this and will probably switch everything to diameter in offseason, but I'm not sure when I will get to that.
