passed to the website.
Added session making code.
Added DB pool, added another tutorial link.
Moved DSN string in db_config, as a composite of other atrributes.
Implementations from defuze.
Turned orm directory into a package.
Added orm in main.py. Some syntax fixes to make things work. Not yet ok.
Removed Base inheritance in TableTemplate.

All mappings now inherit from two classes: TableTemplate and Base.
Fixed some function calls. Pretty much running.
Added MySQL-python to requirements.txt.
Errant underscore in db schema.
More packages.
Removed the charset declaration in TableTemplate.

It was causing TypeErrors so apparently they do not belong there.
The proper charset declaration.
