//psuedo code: First part using three different functions to execute commands so that fahrenheit is inputed and calculated, along with Celcius if 
// inputed and then changed back into Fahrenheit. After that, windspeed is asked to be inputed and then calculated with fahrenheit to produce 
// the windchill.
