jsrender is part of a jsrequire based module system to render data via javascipt inside
reagent components. Typically custom ui renderers would use it:
[jsrender custom-module data]

equivalent to pinkgorilla.ui.renderer, but for clojurescript
renders clojurescript data structure to html

 For pinkie tag injection we need a more up to date version
of walk.
