@nickwallen My intent here is to add a hook in the profiler on tick. Would
you take a look and make sure I'm doing this right? I'm interested
specifically in the empty hashmap here. I'd like to ensure that the current
message is being passed in on tick, but I fear it won't be the case.

> 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).
