about_hashes

* hashes can be created using {}
* no keys will equal nil 
* use fetch when hash is too big and you want
  to find specific key
* unable to answer reasoning - ask in class
  # Bonus Question: Why was "expected" broken out  
  into a variable
  # rather than used as a literal?
* order does not matter in bases using keys
* hash are apart of array class
* you can search for both keys and values using
  .include method
* combining bases will replace designated symbols
* you can set a default value for hash but also
  chose which one you want to be different
* using brackets in hash will set all keys to same 
  values, which can increase because your just    
  adding to array
* inserting a block for default value will let you 
  have separate values to each array(value) /  
  symbol
