Refactor. 
Family: Changed getAllChildren() to return the array.  Previous return object was not clear (or useful).
OutputDisplayer: Added a different person lookup method so it can be re-used for Death before Marr.  This required changing the family printout loop.  It's messy because old code was retained. But after the merge during the next update to OutputDisplayer will clean up everything.
Refactor. 
FamilyTest: Changed b/c getAllChildren changed.
GedcomProcessServiceTest: Changed to do a line by line compare.  Displays both lines if there is a failure.  Note, output will go verbose if line by line gets out of sync, but that should be OK.
