// **** NOTE ****
// It turns out that Apple has an API for this: UnitTemperature
// More information at: https://developer.apple.com/documentation/foundation/unittemperature

// Convert temperature to Fahrenheit, Celcius and Kelvin
// Note: This was quickly put together and verifying the results is warranted.  

// FIXME: Kelvin converts to celcius, which will most assuredly produce incorrect
// results, as no attempt was made to determine what unit is coming in.
