class Inflector in Zircon Profile 8

Doctrine inflector has static methods for inflecting text.

The methods in these classes are from several different sources collected across several different php projects and several different authors. The original author names and emails are not known.

Pluralize & Singularize implementation are borrowed from CakePHP with some modifications.
