/*
RULES OF LIGHT:

light = 1.0 (0.999-1.001) is SUNLIGHT. It goes downwards infinitely from
infinite highness and stops when it first hits a non-transparent node.
The lighting of the node it hits is 0.

Other LIGHT SOURCES have a light value of UNDER 0.999.

Light diminishes at a constant factor between nodes.

TODO: Should there be a common container to be parent of map, sector and block?
