Ants works!

Some notes:

* cro was broken from a floating point point of view due to ordering of operations
* I added a "noop" function for plotting.  That gives us something easy to search for in our code for things we aren't implementing yet (like UI affecting functions such as plot)
* I only repeat 10, so I'm not doing the full benchmark.  I tried, but my computer is too slow and it was taking forever
