	; Simple array Index routine
	; Number of total indexes dimensions - 1 at beginning of memory
	; HL = Start of array memory (First two bytes contains N-1 dimensions)
	; Dimension values on the stack, (top of the stack, highest dimension)
	; E.g. A(2, 4) -> PUSH <4>; PUSH <2>
	; For any array of N dimension A(aN-1, ..., a1, a0)
	; and dimensions D[bN-1, ..., b1, b0], the offset is calculated as
	; O = [a0 + b0 * (a1 + b1 * (a2 + ... bN-2(aN-1)))]
; What I will do here is to calculate the following sequence:
	; ((aN-1 * bN-2) + aN-2) * bN-3 + ...
