add support for probes

[gretac]

• ref #17
• target ensemble sends messages to the probe
• probe sends all recoded data to the administrator at the end of the simulation
• client code needs to access recorded probe data from the network for spike

tests are failing because of matplotlib:

we should be able to toggle showing plots or not...or else Travis will run the matplotlib stuff all the time

[gretac]

I will comment out the probe result plotting and instead just print the recorded values for the Travis automated tests. We want to be able to compare the numbers that are recorded and ensure they are identical in our automated tests. However, the plotting will be left in the files commented in case we are doing manual testing during development and want to look at the graphs to see approximate results.

[hudon]

travis will fail on this because we're waiting on #37, but make test passes on my machine
