Detailed Description

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

Array[L][X][Y] of value. Brute-force. High memory consumption. Rather fast except when working with several labels.

Note that 4000*4000*16 is upper limit on my 8Gb laptop (2Gb). Note that 2000*2000*64 is upper limit on my 8Gb laptop (2Gb).
