  Write a function isSquare(number) that takes in a number and returns true if the
  number is a perfect square, false otherwise. A perfect square is a number that is
  the result of squaring another number. For example, 3 * 3 is 9, so 9 is perfect
  square. 4 * 4 is 16, so 16 is a perfect square. 18 is not a perfect square.
  
  Examples:
  
  isSquare(7) => false
  isSquare(15) => false
  isSquare(18) => false
  isSquare(25) => true
  isSquare(36) => true
  isSquare(9) => true
  isSquare(16) => true
