@Override
	public int getAlignment(int radix) {
		return (int) (start.getOffset() % radix);
	}
Returns the natural alignment (offset) for the given radix. If there is no natural alignment,
it should return 0. A natural alignment only exists if there is some underlying indexing
structure that isn't based at 0. For example, if the underlying structure is address based
and the starting address is not 0, then the natural alignment is the address offset mod the
radix (if the starting address is 10 and the radix is 4, then the alignment is 2)).
