/*	Documentation of Research Done for this Plugin:
	Registration URL (based on a root install in http://localhost):
	WordPress 3.6.1 without jonradio Private Site installed
	Single Site - not a network
		http://localhost/wp-login.php?action=register
	Primary Site of a Network
		http://localhost/wp-signup.php
	Secondary Site of a Network
		http://localhost/wp-signup.php
	This last URL needs a lot of thought because it means that what begins on one site ends up on another.

	WordPress 3.7-beta without jonradio Private Site installed
	Single Site - not a network
		http://localhost/wp-login.php?action=register
	Primary Site of a Network
		http://localhost/wp-signup.php
	Secondary Site of a Network
		http://localhost/wp-signup.php
	
	WordPress 3.0.0 without jonradio Private Site installed
	Single Site - not a network
		http://localhost/wp-login.php?action=register
	Primary Site of a Network
		http://localhost/wp-signup.php
	Secondary Site of a Network
		http://localhost/wp-signup.php
	
	wp_registration_url() was not available prior to WordPress Version 3.6.0
	
	Self-Registration allows potential Users to Register their own ID and Password without Administrator intervention or knowledge.
	It is controlled by:
		get_option( 'users_can_register' ) - non-Network
			'1' - allows Self-Registration
			'0' - no Self-Registration
		get_site_option( 'registration' ) - Network (Multisite)
			'user' - allows Self-Registration
			'none' - no Self-Registration
			'blog' - Users can create new Sites in a Network
			'all' - allows Self-Registration and the creation of new Sites in a Network
