Provides a thread-local transactional wrapper around the root Engine class.

The ``threadlocal`` module is invoked when using the
``strategy="threadlocal"`` flag with :func:`~sqlalchemy.engine.create_engine`.
This module is semi-private and is invoked automatically when the threadlocal
engine strategy is used.

The 'threadlocal' engine strategy is deprecated, and will be removed in a future release.  The strategy is no longer relevant to modern usage patterns (including that of the ORM :class:`.Session` object) which make use of a :class:`.Connection` object in order to invoke statements.c
