	AUTHOR: Ryo Chijiiwa <ryo@ilohamail.org>
	FILE: source/index.php
	PURPOSE:
		1. Provides interface for logging in.
		2. Authenticates user/password for given IMAP server
		3. Initiates session
	PRE-CONDITIONS:
		$user - IMAP account name
		$password - IMAP account password
		$host - IMAP server
	COMMENTS:
		Modify form tags for "host" as required.
		For an example, if you only want the program to be used to log into specific 
		servers, you can use "select" lists (if multiple), or "hidden" (if single) tags.
		Alternatively, simply show a text box to have the user specify the server.
