windChill() - Given a temperature (in degrees Fahrenheit) and wind speed (in miles per hour), you are to calculate the wind-chill factor (i.e., the apparent temperature). Note that if the wind speed is 3 miles per hour or less, then the wind-chill is the same as the temperature. Otherwise, the wind-chill is defined by the following formula: 35.74 + 0.6215*temp + (0.4275*temp - 35.75)*wind^0.16. Your calculated wind-chill should be rounded to the nearest integer.
