football.db - New Database Schema Docu for Tables, Columns etc. (Generated w/ schemadoc)

[Gerald Bauer]

Hello,

I've added a new /schema repo that holds the new (auto-)generated
football.db database schema documentation [1] for tables, columns,
etc.

Cheers.

PS: The schema docu gets (auto-)generated by a new command line tool,
that is, schemadoc [2].
