Echo JS 0.11.0

In the end, people will gather around in the box tooling, until something better enough to break out comes along.  In this case, Jest includes assertions, and the testing syntax isn't completely alien... it also offers integration of babel easily, and istanbul in the box.  Yeah, it's more configuration, but that isn't always a bad thing.

It's pretty cyclical... as things approach a good point of equilibrium.  As long as choice remains, and it's easy enough to change many things later...  I've seen things change out several times the past few years.  And some of the composite tooling seems to be using other tools under the covers, or you can use those alone.
