-The server is what reacts to user interaction whithin the interface. Once started it will first parse the given [clarion](https://github.molgen.mpg.de/loosolab/wilson-apps/wiki/CLARION-Format/) file into a clarion object, performing validation steps in the process. Next the server parts of the respecting [modules](https://shiny.rstudio.com/articles/modules.html) defined in the UI (notice the matching ids) are loaded. Whereas the filter module bluntly accepts the data object with `clarion = data` the plot module receives its data via `clarion = reactive(filtered_data()$object)`. Wrapping in `reactive()` is due to the fact, that the filtered data object returned from the filter module is in a reactive context which essentially means shiny 'knows' when this variable changes.
