Detailed Description

template<typename Value, unsigned int L, unsigned int X, unsigned int Y>
class ArrayXYOfMap< Value, L, X, Y >

Array[X][Y] of map<L,Value> Intermediate approach. Slower (between 30% and 40%) than ArrayXYOfLabelledMap and takes 50% to 100% twice as much place.

Note that 4000*4000*16 takes 861Mb. Note that 2000*2000*64 takes 218Mb.
