ropebwt 20130801: New formula

RopeBWT is the predecessor of ropeBWT2. The old version implements
three separate algorithms: in-memory BCR, single-string incremental
FM-index on top of a B+ tree and single-string incremental FM-index on
top of a red-black tree. BCR is later extended to support RLO and RCLO
as well.
