NuiCookie

##Abstract nui.cookie is a helper method to set and read cookies. It is designed to give simple and predictable return values. It can be mixed into nui plugins or used straight up on a page.

It uses CRUD (create, read, update, destroy) conventions.

##Public methods

• nui.cookie.create('name', 'value', days, 'path') - returns the newly created cookie
• nui.cookie.read('name') - returns the value of the cookie if the cookie exist - otherwise returns null.
• nui.cookie.update('name', 'value', days, 'path') - checks if cookie exists - if it does it updates the cookie value.
• nui.cookie.destroy('name','path')- Expires the cookie (browser will delete cookie).

##Examles

// Javascript:

// create a cookie	
nui.cookie.create('name', 'value', days, 'path');

nui.cookie.create('foo', 'bar', 14, 'finland');

// Read a cookie

nui.cookie.read('foo');

//  returns 'bar'

nui.cookie.read('doesnotexist');

// returns null.

// to check for a cookie:
if (nui.cookie.read('foo')){
	// User has cookie named foo. Bail!
}
