'''SQLAlchemy versioned domain model extension.

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

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).

Some useful links:



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.
