Detailed Description

A map (spatial distribution of data) returning the nearest neighbor to the queried position
Stores position referenced objects.

z_weight is a weight, how important vertical differences are for neighborhood.
          0 means only horizontal distance and a high value only uses the height as a distance measure.
The distance to be minimized is calculated as: sqrt((x1-x2)**2+(y1-y2)**2)+abs(z1-z2)*z_weight

__call__()

__call__	(		self,
			x,
			y,
			z = 0 )

 returns the nearest neighbor object to the given position
    The distance to be minimized is calculated as: sqrt((x1-x2)**2+(y1-y2)**2)+abs(z1-z2)*z_weight 

Reimplemented from Map.
