Code and documentation outdated

[lrapp-adan]

One can install v2.0.4 via pip (which is required for the current iris-web version 2.4.11), but somehow the code here on GitHub (v2.0.1) and the official python API client documentation (v2.0.2) seem to be outdated. Unfortunately, there were breaking changes in the case note handling. Thus, it would be great to update the code and documentation here on GitHub.
