'''SQLAlchemy versioned domain model extension.

For general information about versioned domain models see the root vdm package
docstring.

Implementation Notes
====================

SQLAlchemy conveniently provides its own Session object which can be used as
the 'session' for the vdm (i.e. the object which holds the current revision).

TODO
====

1. How do we commit revisions (do we need to).
    * At very least do we not need to update timestamps?
    * support for state of revision (active, deleted (spam), in-progress etc)

2. Support for composite primary keys.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
