Release 1.3.0
first patch for CTC (#1) * patch for CTC Updated setup.py for the various bits about author etc. Importantly changed to python 3.10 and moved from distutils to setuptools. Pretty simple. Ran find to locate all the instances of the Mutable class and changed it to be abc.Mutable via sed. Again, not overly exciting. Added a pypi.sh tool so that I can quickly build and install new versions without having to rely on my memory.
