application of cljs-start lein template

Hi Tero,
I tested my cljs-start lein-template with your lib. Here is the result. I did not change anything in the code, just the directory layout. I instrumented your lib with austin and introduced clojurescript.test (both from Chas Emerick). 

If you have time let me know what you think about it. To see what cljs-start does, you can read its README.

My best
