Started separating the object mapping into two types: literal and class.
The 'literal', or classic following from SQLAlchemy terminology, mapping
first explicitly defines the tables and columns and then maps an entity,
or object, to the table. The 'class', or declarative following from
SQLAlchemy terminology, form creates a constructor function based on a
table definition and maps all objects created with the constructor to
the table automatically. The split between the two was started, with
many ideas being added but fully implemented or at all.
