private AddressSetView getDetailsAddressSet(ProgramLocation p1Location) {
		Address p1Address = p1Location.getAddress();

	}
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 p1Location the program location in 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.
