Numbert sort device O(N)

Description

// number sorting device, sequential, 2*N clocks for N
// linear buffer implementation
// sequential, stable, can be partly readed, decreasing order
// reset is not implemented
// see sort_stack_algorithm.png to catch the idea

// number sorting, tree-like implementation, sequential,
// energy efficient (theoreticaly)
// see sort_tree_algorithm.png to catch the idea
