Running annotation queries on annotated Succinct data.

import edu.berkeley.cs.succinct.annot._

val succinctAnnot =  AnnotatedSuccinctRDD(sc, "/path/to/succinct/data")
// The following is equivalent to {ge^sentence} OVER /remains|still unknown|unclear|uncertain/
// The output is an RDD of Annotation objects, which is just a wrapper holding the annotation data (id, ranges, etc.)
val res = succinctAnnot.regexOver("(remains|is|still) (unknown|unclear|uncertain)", "ge", "sentence")
res.take(20)          // Take first 20 results
res.count             // Iterate through all results
