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.

pre-configured managers for the full class hierarchy. Mappers
