Return the active application element, if it currently exists in the DOM

Return a flag for whether the Application instance is currently rendered

Render the Application by evaluating it's HTML template against the object of data provided by the getData method If the Application is rendered as a pop-out window, wrap the contained HTML in an outer frame with window controls
Add the rendered application to the DOM if it is not already present. If false, the Application will only be re-rendered if it is already present.
Additional rendering options which are applied to customize the way that the Application is rendered in the DOM.
The rendered Application instance
After rendering, activate event listeners which provide interactivity for the Application. This is where user-defined Application subclasses should attach their event-handling logic.

Whether to trigger tab-change callback functions

A Promise which resolves once the minimization action has completed
Maximize the pop-out window, expanding it to its original size Take no action for applications which are not of the pop-out variety or are already maximized
A Promise which resolves once the maximization action has completed
Set the application position and store its new location. Returns the updated position object for the application containing the new values.

Specify the set of config buttons which should appear in the Application header. Buttons should be returned as an Array of objects. The header buttons which are added to the application can be modified by the getApplicationHeaderButtons hook.
Activate required listeners which must be enabled on every Application. These are internal interactions which should not be overridden by downstream subclasses.
