[Developers] Test suite criteria

The Cactus test suites check for differences using both the absolute  
and the relative differences.  A test is marked as failing if either  
of the differences is too large.  There was one case where the  
relative error was 1e-15, but the absolute error 1e-12 (since the  
value itself was about 1000), and thus the test was marked as  
failing.  However, things don't get much better than a relative  
difference of 1e-15.

I suggest to change the criteria from "either" to "both".  That is, a  
test would fail only if both the absolute and relative differences  
are too large.
