This is an unfinished test based upon my thoughts of the Edinburgh walk.
right click in the field to create targets, left click and you change a
fields accessibility(walkable,unbuild/not walkable,build), drag to create an
area of black pixels, double click and the black pixel will jump to
the least connected spot.
A black pixel represents a building, a white pixel represents open space.
show connectivity produces a map showing the connectivity of a pixel. A pixel
is well connected if angles along the path, between the way you walk and the
direction to the targets, are small (see drawing .pdf).
maximum angle if you hit the rebuild button this angle specifies at what angle the
deviation gets to big and the buildingscape starts to get rebuilt.
neighbors defines how many black pixel can be adjacent to another.

Press 3 and the scene will render in 3d. UP/DOWN/LEFT/RIGHT will help you navigating
through the scene. Q/A changes your z-position. Press W/S to look up or down.
