As stated in #20 we want to refactor the frontend code to be able to extend the plugin functionality fast and reliable. The POC will be implemented in branch softvis3d_react_example and then hopefully merged into master.

Acceptance criteria:

• Integrate a simple react component somewhere in the angular app view
• Write a plain typescript class which can be used within the current angular app view
• Write simple tests with karma/jasmine for the typescript class
