Added CSV change to CDL.java

[brianrussell2]

Adding my code for the GitHub issue I described.

Looks reasonable. Need to run it through the unit tests, and add some cases to exercise the new code. @captainIowa you are welcome to take the lead on that if you want. The unit tests are located in https://github.com/stleary/JSON-Java-unit-test. Otherwise I will take care of it when I get a chance.

@stleary I can take a run at it this weekend.

@stleary I ran my changes through the unit tests and added some additional ones to exercise my code changes. Do I need to post the results of the unit tests somewhere or take any additional steps?

[stleary]

@captainIowa thanks, no other actions are needed, reviewers will take a look and let you know if there are any concerns.

The change looks good to me upon review. I did not check out and run the code myself though. As long as all the new tests pass, I think this is good to go.

What problem does this code solve?
Support in the CDL module for parsing embedded quotes in CSV files to maintain compatibility with RFC 4180. For additional discussion, see #217.

Changes to the API?
No.

Does it break the unit tests?
No, but new unit tests will be added after this commit. Those tests will fail unless this code is committed. See stleary/JSON-Java-unit-test#45.

Will this require a new release?
No, this will be rolled into the next release, which is not yet scheduled.

Should the documentation be updated?
No, this is an internal bug fix to maintain compatibility with the spec.
