An element that displays in one quadrant of the screen.

The current quadrant is stored in a data attribute [data-quadrant] as the name of the quadrant (@see Quadrant)

Changing the quadrant via Quadrant->setQuadrant will emit the event ChangeQuadrant with the parameters being the new quadrant and the old quadrant.

Changing the quadrant will not affect other elements: this is the responsisibility of the parent.
