MI Example Fails

[neeshjaa]

The page contains an example:

SELECT
  MUTUAL INFORMATION OF Apogee_km < 1000
  WITH Perigee_km < 1000
  UNDER satellites_model
FROM satellites

However this fails in the current implementation:

IQL> select mutual information of Apogee < 1000 with Perigee < 1000 under model from data
No implementation of method: :mutual-info of protocol: #'inferenceql.inference.gpm.proto/MutualInfo found for class: inferenceql.inference.gpm.crosscat.XCat
