/** \class DebuggingTestStat
    \ingroup Roostats
 
DebuggingTestStat is a simple implementation of the DistributionCreator interface used for debugging.
The sampling distribution is uniformly random between [0,1] and is INDEPENDENT of the data.  So it is not useful
for true statistical tests, but it is useful for debugging.
