This module is usually not directly visible to user applications, but
defines a large part of the ORM's interactivity.

instrumentation.py deals with registration of end-user classes
for state tracking.   It interacts closely with state.py
and attributes.py which establish per-instance and per-class-attribute
instrumentation, respectively.

The class instrumentation system can be customized on a per-class
or global basis using the :mod:`sqlalchemy.ext.instrumentation`
module, which provides the means to build and specify
alternate instrumentation forms.

.. versionchanged: 0.8
   The instrumentation extension system was moved out of the
   ORM and into the external :mod:`sqlalchemy.ext.instrumentation`
   package.  When that package is imported, it installs
   itself within sqlalchemy.orm so that its more comprehensive
   resolution mechanics take effect.
