*  Using the JavaScript language, have the function CheckNums(num1,num2) take both     *
*  parameters being passed and return the string true if num2 is greater than num1,    *
*  otherwise return the string false. If the parameter values are equal to each other  *
*  then return the string -1                                                           *
