//  RBBISetBuilder   Handles processing of Unicode Sets from RBBI rules.
//
//      Starting with the rules parse tree from the scanner,
//
//                   -  Enumerate the set of UnicodeSets that are referenced
//                      by the RBBI rules.
//                   -  compute a derived set of non-overlapping UnicodeSets
//                      that will correspond to columns in the state table for
//                      the RBBI execution engine.
//                   -  construct the trie table that maps input characters
//                      to set numbers in the non-overlapping set of sets.
