/**
 * AngularJS service that handles the popover query parameter for Piwik's angular code.
 *
 * If the popover parameter's first part is the name of an existing AngularJS directive,
 * a dialog is created using ngDialog with the contents being an element with that directive.
 * The other parts of the parameter are treated as attributes for the element, eg,
 * `"mydirective:myparam=val:myotherparam=val2"`.
 *
 * It should not be necessary to use this service directly, instead the piwik-dialogtoggler
 * directive should be used.
 *
 * TODO: popover as a query parameter refers less to dialogs and more to any popup window
 *       (ie, not necessarily modal). should replace it w/ 'dialog' or maybe 'modal'.
