I add the generation of a CallFacet to the example.py. Changes include:
FacetCall: added observable:participant, deleted allocationStatus (it would be useful to add a property indicating how the Artifact has been extracted: interpreted or carved)
FacetAccount: the property accountIssuer is now an ObservableObject type not a string
FacetPhoneAccount: deleted the displayName property
