Outstanding issues:

• [x] Build proper docker image
• [x] Get Bokeh to work again
• [x] Cleanup commit history
• [x] Introduce routing
• [x] Add non-next linting rules
• [x] Add automatic version identifier
• [x] Consider introducing modules (Experiment, Chooser and Sample App) Should be deferred to separate issue
