      public MetaConfig(Map<String,Object> config, Boolean shouldSampleByDefault)
      A map of values, with the following keys and meanings. - includeLabels: a list of strings, which are allowlisted node labels. If this list is specified **only these labels** will be examined. - includeRels: a list of strings, which are allowlisted rel types. If this list is specified, **only these reltypes** will be examined. - excludeLabels: a list of strings, which are node labels. This works like a denylist: if listed here, the thing won't be considered. Everything else (subject to the allowlist) will be. - excludeRels: a list of strings, which are relationship types. This works like a denylist: if listed here, the thing won't be considered. Everything else (subject to the allowlist) will be. - sample: a long number, i.e. "1 in (SAMPLE)". If set to 1000 this means that every 1000th node will be examined. It does **not** mean that a total of 1000 nodes will be sampled. - maxRels: the maximum number of relationships to look at per Node Label.
