-- Integrated scopt with PostgresExporter, for parsing command line options.

Signed off by Mark Farrell<markfarr2011@gmail.com>
-- Added StreamParser, functioning nearly the same as BerkeleyParser in the
berkeleyparser project. Any input and output streams can be specified rather than being
restricted to stdin and stdout.
-- Deleted LazyCache and LazyCacheBlurb, as well as test.sh and test/.
If the output of the berkeleyparser is to be inspected in the future,
it is better to use the tool itself and leave data outside this project.
-- Added Blurb, to tokenize a blurb of text into individual sentences.
