*  Using the JavaScript language, have the function TimeConvert(num) take the num      *
*  parameter being passed and return the number of hours and minutes the parameter     *
*  converts to (ie. if num = 63 then the output should be 1:3). Separate the number    *
*  of hours and minutes with a colon.                                                  *

*  There are 60 minutes in an hour. To find the number of hours divide the num by      *
*  60 and use the Math.floor to convert to whole hours.  Next use the modulus          *
*  function to get the minutes.
*                                                                                      *

*    1) Get hours by dividing num by 60 to get whole number of hours                   *
*    2) Get minutes by using modulus function                                          *
*    3) Combine hours and minutes in required format and return as answer              *
