		}
		return null;
	}
Gets the address set where detailed differences will be determined for details at the
indicated address. An address set is returned since the indicated address may be in different
sized code units in each of the two programs.

@param p1Address the current address from program1 where details are desired.
@return the address set for code units containing that address within the programs being
        compared to determine differences. Otherwise null if a diff of two programs isn't
        being performed.
