 * # WooCommerce Customer/Order CSV Export
 *
 * ## Plugin Overview
 *
 * This plugin exports customers and orders in CSV format. Customers can be exported via
 * CSV Export > Export and are selected from orders in a selectable date range. Orders can be
 * exported in bulk from CSV Export > Export and from the Orders / Edit Order screen, as well as auto-exported
 * via FTP and HTTP POST on a recurring schedule.
 *
 * ## Class Description
 *
 * The main class for Customer/Order CSV Export. This class handles general lifecycle and setup functions, as well
 * as marking new orders as un-exported and handling the AJAX export action on the Order screen.
 *
 * ## Admin Considerations
 *
 * A 'CSV Export' sub-menu item is added under 'WooCommerce', with two tabs: 'Export' for handling bulk exports of
 * both customers and orders, and 'Settings' which define the output format for both customers and orders, as well as
 * auto-export interval & FTP/HTTP POST settings.
 *
 * An 'Export Status' column is added to the Orders list table, along with a new order action icon for downloading the order
 * to a CSV. Another order action is added to the Edit Order screen under the order actions select box.
 *
 * ## Database
