Introducing Migrations to CodeIgniter

Hi

Thanks for this - but I can't get it to work, even straight out of the box. I'm getting:

Fatal error: Call to undefined function create_table() in 001_create_articles_schema.php on line 9

I know this relates to using the dbutil helper but I can't see how to get this to work - the wiki isn't very clear:

"Both functions: create_table and drop_table are defined in the dbutil helper. If you do not want to use this helper, you can always call get_instance() to retrieve the CI instance and call each query in the traditional way."

Any help greatly appreciated.

Thanks
