[Users] Hydro_InitExcision par directory has more than just parameter files

[Bernard Kelly]

Hi.

I noticed that the thorn EinsteinInitialData/Hydro_InitExcision has a
"par" subdirectory containing both parfiles *and* the resulting output
directories; it looks just like a second set of test suites, except
presumably they'd never be picked up by the testsuite process. Any
reason why these are there (still true with new 2015_11 release)?

Thanks,

Bernard
