Dynamically created tables are "Classical" SQLAlchemy style unmapped

[gracecodes144]

See reference on SQLAlchemy mapping styles here. I made the switch from constructing class contents dictionaries and then using type to create the class (in "Declarative" style) to creating a "Classical" model class and building it up modularly a while ago, without realizing the difference. There is no problem with this, but I believe it might be confusing for beginning SQLAlchemy users, and would be easy to use the mapping API to create mapped model classes dynamically from the classical ones.

It seems that the mapping API is actually quite difficult. It turns out the Declarative style might be the way to go.
