[geeklog-devel] Draft of schema for GL2

[Tony Bibbs]

Excellent, looks like Vinny more than did his homework on this one (not 
that I doubted him).  I say because of this we should make the comments 
part of the core...that way we can hide the complexity of the 
inserts/deletes from plugin authors.
