Some of these tables are getting complicated, so I have created three
different tables, and this should be sufficient.
Describing it, however, seems to be a lot for source code, and I thought
I would describe it using a literate programming style. We'll see.
I have a semblance of code giving me functions to help me run my D&D
games. The README needs a lot more love, but the code is generally tidy.
Time to add some tables...
