// Pseudo Code:
// 1. Print "Please enter F for Fahrenheit, or C for Celsius"
//      1. Declare constant [Fmax] = 121
//      2. Declare constant [Fmin] = -80
//      3. Declare constant [Cmax] = 49.5
//      4. Declare constant [Cmin] = -62
// 2. Input [Tunit]
// 3. If [Tunit] = F is selected:
//      1. Print "Enter temperature value between -80 and 121 degrees Fahreneit"
//      2. Input [TvalF]
//      3. Clamp TvalF to limits
// 4. If [Tunit] =  C is selected:
//      1. Print "Enter temperature value between -52 and 49.5 degrees Celsius"
//      2. Input [TvalC]
//      3. Clamp TvalC to limits
// 6. Print "Enter a wind speed, in miles per hour, between 0 and 231"
//      1. Declare constant [Wmax] = 231
//      2. Declare constant [Wmin] = 0
//      3. Input [Wspeed]
//      4. Clamp Wspeed to limits
// 7. F input function:
//      1. Declare [FtoCval] = ( [TvalF] - 32 ) * ( 5 / 9 )
//      2. [TvalC] = [FtoCval]
// 8. C input function:
//      1. Declare [CtoFval] = (9 / 5 ) * [TvalC] + 32
//      2. [TvalF] = [CtoFval]
// 9. Windchill function:
//      1. [Wchill] = 35.74 + .6215 * [TvalF] - 35.75 * ( [Wspeed] ^ 0.16 ) + 0.4275 * [TvalF] * ( [Wspeed] ^ 0.16 )
// 10. Print headers "Temperature in F" , "Temperature in C", "Windpseed", "Windchill"
// 11. Print [TvalF] , [TvalC] , [Wspeed] , [Wchill]
//
