/**
* 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.
* @uses apply_filters() Calls filters for most of the $userdata fields with the prefix 'pre_user'. See note above.
* @uses do_action() Calls 'profile_update' hook when updating giving the user's ID
* @uses do_action() Calls 'user_register' hook when creating a new user giving the user's ID
*
* @param array $userdata An array of user data.
* @return int The newly created user's ID.
