/**
* Inflector for pluralize and singularize English nouns.
*
* This Inflector is a port of Ruby on Rails Inflector.
*
* It can be really helpful for developers that want to
* create frameworks based on naming conventions rather than
* configurations.
*
* It was ported to PHP for the Akelos Framework, a
* multilingual Ruby on Rails like framework for PHP that will
* be launched soon.
