Base types API.

Class Emulated Mixin for base types that emulate the behavior of a DB-native type.
Class ExternalType mixin that defines attributes and behaviors specific to third-party datatypes.
Class NativeForEmulated Indicates DB-native types supported by an :class:`.Emulated` type.
Class TypeDecorator Allows the creation of types which add additional functionality to an existing type.
Class TypeEngine The ultimate base class for all SQL datatypes.
Class TypeEngineMixin classes which subclass this can act as "mixin" classes for TypeEngine.
Class UserDefinedType Base for user defined types.
Class Variant deprecated. symbol is present for backwards-compatibility with workaround recipes, however this actual type should not be used.
