Geo function support in Fluo PCJ sparql queries

Rya's Fluo pre-computed joins (PCJ) framework along with Kafka sub/pub gives makes Rya a strong Complex Event Processor (CEP) – taking streaming input statements and generating results to subscribed (kafka topics) queries (PCJ's).
We have identified geo functions as a major enabler for CEP users.
Currently PCJ can handle basic SPARQL filter functions, but not geo functions.
