Detailed Description

Material writer dumping the tracking geometry material map to Json/Cbor.

This uses the ACTS Json plugin (Acts::MaterialMapJsonConverter) to serialise the surface and volume material maps into a Json (and/or Cbor) file. The resulting file can be read back in e.g. by Acts::JsonMaterialDecorator.
