-#  * `application:quit` - Quits the entire application.

-#    running on the system.

-#    that were previously hidden.
-#  * `application:new-window` - Opens a new {AtomWindow} with no {Project}
-#    path.
-#  * `application:new-file` - Creates a new file within the focused window.
-#    Note: only one new file may exist within an {AtomWindow} at a time.
-#  * `application:open` - Prompts the user for a path to open in a new {AtomWindow}
-#  * `application:minimize` - Minimizes the currently focused {AtomWindow}
-#  * `application:zoom` - Expands the window to fill the screen or returns it to
-#    it's original unzoomed size.
-#  * `application:bring-all-windows-to-front` - Brings all {AtomWindow}s to the
-#    the front.
