+ # The Inflector transforms words from singular to plural, class names to table names, modularized class names to ones without,
+ # and class names to foreign keys. The default inflections for pluralization, singularization, and uncountable words are kept
+ # in inflections.rb.
+ #
+ # The Rails core team has stated patches for the inflections library will not be accepted
+ # in order to avoid breaking legacy applications which may be relying on errant inflections.
+ # If you discover an incorrect inflection and require it for your application, you'll need
+ # to correct it yourself (explained below).

+ # A singleton instance of this class is yielded by Inflector.inflections, which can then be used to specify additional

+ # inflect.plural /^(ox)$/i, '\1\2en'
+ # inflect.singular /^(ox)en/i, '\1'
+ #
+ # inflect.irregular 'octopus', 'octopi'
+ #
+ # inflect.uncountable "equipment"
+ # end

+ # New rules are added at the top. So in the example above, the irregular rule for octopus will now be the first of the
