-##
-# = JavaScript Object Notation (JSON)
-#
-# JSON is a lightweight data-interchange format. It is easy for us
-# humans to read and write. Plus, equally simple for machines to generate or parse.
-# JSON is completely language agnostic, making it the ideal interchange format.
-#
-# Built on two universally available structures:
-# 1. A collection of name/value pairs. Often referred to as an _object_, hash table, record, struct, keyed list, or associative array.
-# 2. An ordered list of values. More commonly called an _array_, vector, sequence or list.
-#
-# To read more about JSON visit: http://json.org
-#
-# == Parsing JSON
-#
-# To parse a JSON string received by another application or generated within
-# your existing application:
-#
-# require 'json'
-#
-# my_hash = JSON.parse('{"hello": "goodbye"}')
-# puts my_hash["hello"] => "goodbye"
-#
-# Notice the extra quotes <tt>''</tt> around the hash notation. Ruby expects
-# the argument to be a string and can't convert objects like a hash or array.
-#
-# Ruby converts your string into a hash
-#
-# == Generating JSON
-#
-# Creating a JSON string for communication or serialization is
-# just as simple.
-#
-# require 'json'
-#
-# my_hash = {:hello => "goodbye"}
-# puts JSON.generate(my_hash) => "{\"hello\":\"goodbye\"}"
-#
-# Or an alternative way:
-#
-# require 'json'
-# puts {:hello => "goodbye"}.to_json => "{\"hello\":\"goodbye\"}"
-#
-# <tt>JSON.generate</tt> only allows objects or arrays to be converted
-# to JSON syntax. <tt>to_json</tt>, however, accepts many Ruby classes
-# even though it acts only as a method for serialization:
-#
-# require 'json'
-#
-# 1.to_json => "1"
-#
