Make comparisons between heterogenous and homogenous quantities possible .
And add a test case that fails without this change.
NOTE that the explicit conversion to
quantity<Unit1, Y>is probably not necessary. It definitely isn't necessary if conversion_factor(Unit2(), Unit1()) == 1, and I believe that it is. Unfortunately I haven't been able to verify that through reviewing the code involved in computing the conversion factor.
