sessionId doesn't seem to get set in the text_request_example, even after adding a unique sessionId in the example source code and compiling. If your C++ API is no longer supported, please say so in the README file so that people don't waste their time on it.

On a related note, I had to edit the submodule URL in my repo for git to find and clone the dependent JSON repo.
