Open-Topology.js - Contains code copied from internet - unknown license

We found when scanning our code that the following file:

modules/loader-resources/src/main/resources/assets/js/open-topology.js contains source code that was actually copied from a website which does not have a clear license file.

As such we do not believe the ODL has the rights to ship this file.
