Option to set data source to a json or xml file fetched from remote server or local but executed pho code

Option to use not only local files as json/xml data source, but also external URL (directly or via any local workaround like php script located at wp-content/uploads/gk_nsp_external_data directory).
This would be same as using external rss feed, just another file types

Good idea - added to the v.1.1 milestone ToDo :)
