METRON-562: Add rudimentary statistical outlier detection
With the advent of the profiler, we can now capture state. Furthermore,
with Stellar, we can capture statistical summaries. We should provide
rudimentary outlier detection functionality in the form of Stellar functions
that can operate on captured state from the profiler.
To begin, we should enable simple outlier tests using distance from a
central measure such as Median Absolute Deviation (see
http://www.itl.nist.gov/div898/handbook/eda/section3/eda35h.htm).
