Riak Pipe Example
Test with metic above threshold fitting

Not tested though, need to figure that part out. Might be fine to spin
up a pipe for each one to get an end-to-end test of each fitting and 
the combinations. Seems a bit heavy though.
Create a logic module that doesn’t include Riak

Similar to the gen_server version but this doesn’t rely on a process.
This is much easier to test than using riak_pipe directly
Use more easily testable fitting
Min OK Fitting

Doesn’t (and didn’t) handle anything more than unique by host. Also
doesn’t handle timeouts
State change fitting
