Test code to examine CMIS relationship targetId values before and after uploading a file via Share. Requires [cmislib](https://chemistry.apache.org/python/cmislib.html) 0.5.1 or greater and the files `alfresco.sh`, `ping.py` and `MultipartPostHandler.py` from the latest version of [share-import-export](http://code.google.com/p/share-import-export/)
