Actually LIB_TABLE class allows cascading of table fragments. You do not
even need a globally accessible library table, just put it in the schematic,
and all team members will stumble onto the same LIB_SOURCEs magically.
Well this is a reproduction of information already available elsewhere, and
I have other work to do.
Lastly, if you want your UUID, put it in as a part property, along with your
mother in law's first name if you want, assuming she was, for example, the
author or designer of the part.
