One more thing, I also added a new lifecycle hook for the profiler. Now
you can update the state on the tick. This is needed for MAD because we will
need to refresh the statistical summary of the lookback window that we are
using to compute the MAD. This should become more clear upon the creation of a
README with a worked example, which I owe y'all.
> 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).
