/**
 * UniFi API Browser
 *
 * This tool is for browsing data that is exposed through Ubiquiti's UniFi Controller API,
 * written in PHP, javascript and the Bootstrap CSS framework.
 *
 * Please keep the following in mind:
 * - not all data collections/API endpoints are supported (yet), see the list below of
 *   the currently supported data collections/API endpoints
 * - currently only supports versions 4.x.x of the UniFi Controller software
 * - there is still work to be done to add/improve functionality and usability of this
 *   tool so suggestions/comments are welcome. Please use the github issue list or the
 *   Ubiquiti Community forums for this:
 *   https://community.ubnt.com/t5/UniFi-Wireless/UniFi-API-browser-tool-released/m-p/1392651
