For consistency, rather than reading the json file in again (which this will do), please follow the same strategy used elsewhere to get single copy of configuration object that is in PicoContainer (ask me to explain the dependency injection---I think I can do it very simply, and it is neat!)  Sorry I missed this use of config when I did the example code elsewhere.  I have updated in it develop, where you can update first before doing a new pull request.   Btw, there is a small possibility my updated code may have a problem, as I could not test it with Reeti.  Let me know if this is the case.
