* DatabaseMap is used to model a database.
* The propel.map classes are abstract building-block classes for modeling
* the database at runtime. These classes are similar (a lite version) to the
* propel.engine.database.model classes, which are build-time modeling classes.
* These classes in themselves do not do any database metadata lookups, but instead
* are used by the MapBuilder classes that were generated for your datamodel. The
* MapBuilder that was created for your datamodel build a representation of your
* database by creating instances of the DatabaseMap, TableMap, ColumnMap, etc.
