bool	step_forward ()
	advance forward (NE) through the matrix
bool	step_back ()
	advance backwrd (SW) through the matrix
bool	at_beginning ()
	check if we're at the beginning, that is (0,0)
bool	at_end ()
	check if we're at the end, that is (#columns, #rows)

Public Attributes
const size_t	max_x
	number of columns in the matrix
const size_t	max_y
	number of rows in the matrix
size_t	x
	current x coordinate
size_t	y
	current y coordinate

Detailed Description

a counter for a pair of integers that runs diagonally through a matrix Each time the counter is incremented, x is incremented and y is decremented until either x > #columns (in which case x is set to 0) or y < 0 (in which case y is set to #rows). If either bound is hit, the sum x+y is incremented.

Thus, the counter always runs in directed North East.
