Encapsulation of spongy world (raw input) state. Its primary duty is the creation and maintenance of the graph of (spongy) anchors built up over the space traversed by the camera.

Remarks
Anchor and Edge creation algorithm:
Goal: a simple and robust algorithm that guarantees an even distribution of anchors, fully connected by edges between nearest neighbors with a minimum of redundant edges
For simplicity, the algorithm should be stateless between time steps
Rules * two parameters define spheres MIN and MAX around current position * whenever MIN does not contain any anchors, a new anchor is created * when a new anchor is created is is linked by edges to all anchors within MAX * the MAX radius is 20cm larger than MIN radius which would require 12 m/s beyond world record sprinting speed to cover in one frame * whenever MIN contains more than one anchor, the anchor closest to current position is connected to all others within MIN
