Need to add the details of the calculation into output data's metadata

This is related to #61

Would also be very good if this metadata could be seen from the metadata tab when you look at the properties of an output layer.

Could also list the input data sets and their metadata here. See #38

[uniomni]

Could also list the quality measures here

[uniomni]

Quality measures should be a separate ticket and link to #185 (comment)

Use this ticket from the previous incarnation: AIFDR/riab#48

I'm closing this as the functionality is required as part of issue #697.
