1. Finished updating the documentation.
2. Finished updating examples.
3. Changed the url format on the web_framework example to include "movie"
before the movie id.
4. Added plan caching to the web_framework example.
5. Removed the requirement to place a backslash before the "taking" clause
when it appears on the next line.
6. Changed "nls" to NL_TOK in krbparser.py since the scanner only emits one
NL_TOK if there are multiple newlines in a row (including lines with just
spaces and/or comments).
