I worked out an example in vagrant. Verified that the statistical and
profiler functions can be called from all the relevant places:
* The REPL
* The parser topology
* The enrichment topology
To test this yourself, please check out the README under
`metron-analytics/metron-statistics`
> 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).
