Graphically show positive proximity tests between two or more AABBs

[XORxes-1]

In instances where many AABBs have been positively tested to be in close proximity to one another, there is no way to determine which groups of AABBs they are. A graphical means to show the pairs of AABBs that are in close proximity should be implemented to clarify this ambiguity. Perhaps the use of lines connected to one another may depict this best. UI elements should be added to allow this to be toggled on or off.
