      public static <O> org.aksw.commons.collector.domain.ParallelAggregator<org.apache.jena.sparql.engine.binding.Binding,?,Map<org.apache.jena.sparql.core.Var,O>,?> aggPerVar(org.aksw.commons.collector.domain.ParallelAggregator<org.apache.jena.graph.Node,?,O,?> nodeAgg)
      Given an aggregator for Node input, create a new aggregator that invokes it on-demand for each encountered variable in bindings. Important Note: This method only instantiates accumulators when encountering variables. If e.g. a result set does not bind a variable then it won't be part of the output map. Use aggPerVar(Set, ParallelAggregator) to specify the set of variables for which to perform the given base aggregation.
