Pending Tasks / Clean up

[mohitmv]

1. Finishing AParse.
   1. Add a really good documentation of AParse.
   2. Add the experiment's benchmark with other parsers.
   3. Make the parser-v1 flow work well
   4. Improve the AParseMachine Traverser code.
   5. Add much more test coverage.
   6. Create the research paper for the new approach of parsing and describe the AParse grammar very well.
   7. Develop C++ parser using AParse.
   8. Add support for rolling back while feeding tokens in Aparse-machine traverser.
   9. Track the proposed tasks in Github itself.
2. AParse Library
   10. AparseMachine must also contain the string maps. In the case of DebugString, we should include the strings. This string map should be passed to NFABuilder as well. In the future NFABuilder can be separated out as a utility.
