Added a tremendous amount of documentation for clientWebControl in clientDocs.md
Reformed and updated the `documentation.md` file, including the new method, `createProcess`.
Additionally, added isAlive() as a passthrough to the pexpect.isalive() method for better checking of the status of processes. That's how the status of processes is now returned through the API as well.
Most importantly, made many changes to testPollPage.html, fixing up and reforming many of the small, often more subtle bugs that it had. (I still hate Javascript, just a little bit less now)
