type: String
desc: The subject string.

> plural

type: String
desc: Overrides normal output with said String.(optional)

#### Example code

var inflection = require( 'inflection' );

inflection.pluralize( 'person' ); // === 'people'
inflection.pluralize( 'octopus' ); // === "octopi"
inflection.pluralize( 'Hat' ); // === 'Hats'
inflection.pluralize( 'person', 'guys' ); // === 'guys'

$3

This function adds singularization support to every String object.

#### Arguments

> str

type: String
desc: The subject string.

> singular

type: String
desc: Overrides normal output with said String.(optional)

#### Example code

var inflection = require( 'inflection' );

inflection.singularize( 'people' ); // === 'person'
inflection.singularize( 'octopi' ); // === "octopus"
inflection.singularize( 'Hats' ); // === 'Hat'

$3

This function will pluralize or singularlize a String appropriately based on an integer value.

#### Arguments
