Functions/Subroutines
integer, dimension(ccounttotal, size(dmax))	enumerate_combinations (dmax, dsum, cCountTotal)
	Service routines for counting and enumerating combinations of a vector (i_1, ..., i_n), with the range of every component i_j is 0 <= i_j <= d_j and for the sum of all components holds sum(i_j) = dsum for a given value of dsum.
subroutine	allocate_combinations (dmax, dsum, comb)
	Convenience routine: allocate and populate an array with all possible combinations.

integer,dimension(ccounttotal, size(dmax)) itm_combinations::enumerate_combinations	(	integer,dimension(:),intent(in)	dmax,
		integer,intent(in)	dsum,
		integer,intent(in)	cCountTotal
	)

Service routines for counting and enumerating combinations of a vector (i_1, ..., i_n), with the range of every component i_j is 0 <= i_j <= d_j and for the sum of all components holds sum(i_j) = dsum for a given value of dsum.

These routines are used to build lists of all possible object classes of a given dimension for a given grid. d_j is then the dimension of space j (stored in the vector dmax), and dsum the dimension of the grid objects under consideration. Compute the number of possible combinations for the vector. Build a list of all possible combinations of the vector.
