  // Given an array of one's and zero's convert the equivalent binary value to an integer.
  
  // Eg: [0, 0, 0, 1] is treated as 0001 which is the binary representation of 1
  
  // Examples: Testing: [0, 0, 0, 1] ==> 1
  //           Testing: [0, 0, 1, 0] ==> 2
  //           Testing: [0, 1, 0, 1] ==> 5
  //           Testing: [1, 0, 0, 1] ==> 9
  //           Testing: [0, 0, 1, 0] ==> 2
  //           Testing: [0, 1, 1, 0] ==> 6
  //           Testing: [1, 1, 1, 1] ==> 15
  //           Testing: [1, 0, 1, 1] ==> 11
