foamDictionary executions are now wrapped by runApplication like any
other execution so that they do not print during a test loop.
foamDictionary does not produce a conforming log, however, so
log.foamDictionary has been filtered out of the formation of the test
loop report so that false failures are not reported.
The initial set of cases in the test directory are aimed at testing the
reactingEulerFoam populationBalance functionality.
