Add option to specify max number of CDAs to generate
Add more comments
replaced teshdwh by current_database() when setting the search_path
changed inner joins with Person to outer joins, so we get results when there are only Roles, no Entities in de CDAs
added ONLY to joins with Participation to speed up stream_etl_observation_evn(). The CDA generator does not generate ManagedParticipation's, so we can skip these.
fixed the skipping almost all CD observations by splitting the single new_observation_evn view into two views: one for PQs and one for CDs
corrected call to format() function
added indexes to speed up ETL queries
