Documentation: Include how to run Liquibase within Java itself.

General Discussion

The documentation explains running liquibase in the following modes:

    Ant
    Maven
    Spring
    Grails
    Servlet Listener
    Command Line

This misses a simply running it within Java itself.  Could this be added to the documentation?

I would recommend you look at the SpringLiquibase class, specifically the afterPropertiesSet() method. This is a pretty good example on how to run Liquibase directly from Java.
