Title: Learned all about nil in branch 65851396_about_nil_master

* Learned that nil is an object (unlike NULL in other languages) and that it has a few methods defined on it
(nil?, to_s, inspect).
* Learned that if a method that nil doesn't know is called on it, it will thrown an undefined method or
NoMethodError
