/**
 * wp_insert_user() - Insert an user into the database.
 *
 * Can update a current user or insert a new user based on whether
 * the user's ID is present.
 *
 * Can be used to update the user's info (see below), set the user's
 * role, and set the user's preference on whether they want the rich
 * editor on.
 *
 * Most of the $userdata array fields have filters associated with
 * the values. The exceptions are 'rich_editing', 'role', 'jabber',
 * 'aim', 'yim', 'user_registered', and 'ID'. The filters have the
 * prefix 'pre_user_' followed by the field name. An example using
 * 'description' would have the filter called, 'pre_user_description'
 * that can be hooked into.
 *
 * The $userdata array can contain the following fields:
 * 'ID' - An integer that will be used for updating an existing user.
 * 'user_pass' - A string that contains the plain text password for the user.
 * 'user_login' - A string that contains the user's username for logging in.
 * 'user_nicename' - A string that contains a nicer looking name for the user.
 *		The default is the user's username.
 * 'user_url' - A string containing the user's URL for the user's web site.
 * 'user_email' - A string containing the user's email address.
 * 'display_name' - A string that will be shown on the site. Defaults to user's username.
 *		It is likely that you will want to change this, for both appearance and security
 *		through obscurity (that is if you don't use and delete the default 'admin' user).
 * 'nickname' - The user's nickname, defaults to the user's username.
 * 'first_name' - The user's first name.
 * 'last_name' - The user's last name.
 * 'description' - A string containing content about the user.
 * 'rich_editing' - A string for whether to enable the rich editor or not. False if not
 *		empty.
 * 'user_registered' - The date the user registered. Format is 'Y-m-d H:i:s'.
 * 'role' - A string used to set the user's role.
 * 'jabber' - User's Jabber account.
 * 'aim' - User's AOL IM account.
 * 'yim' - User's Yahoo IM account.
 *
 * @since 2.0.0
 * @uses $wpdb WordPress database layer.
