why dsl? 
create functions/macros that allow to easily create renderable data structures

The data that gets passed to a renderer has to be verbose, because it allows 
to configure all options. The dsl allows us to build the data that gets displayed
in an easy manner.

dsl stolen from: https://github.com/wiseman/leaflet-gorilla
- currently not working, because:
  1. we need to calculate map center
  2. wiseman syntax does not allow to specify all params needed

reagent component to render highchart-spec via highcharts.js
Usage:  [:highchart spec-as-clj-data]

Highchart renderer is a pure javascript renderer, the conversion
of the spec as clj-data to javascript is done in the render-js component

custom components need to define a javascript-module
module-test is a very simple sample that just renders the data as
JSON to the dom node that is passed.
In early state component development this is helpful.
