  //PREP
  
  //Parameters: hexString, a string
  
  //Return value: 3 numbers, r,g,and b
  
  //Example: #FF9933 => [FF,99,33] => [255,99,51]
  
  //Psuedocode:
  
  //1. split each two digits into an array
  
  //2. convert each two digits of array to base 10
  
  //3. return each of the base 10 digits
