 - ensures (almost) perfect compatibility between the openMINDS API and the fairgraph API,

   importing "fairgraph.openminds" instead of "openminds.v4" when they wish to upload
   metadata to the Knowledge Graph.

+- adds functionality for working with local JSON-LD files in fairgraph.

+- adds the :class:`Collection`, which has the functionality of the equivalent class in openMINDS-Python,

 The documentation has been refreshed and extended.

 This version of fairgraph provides the openMINDS v4 schemas.
