This will allow you to create migration classes for use with the "yiic migrate" command for any or all tables in a database schema.
It currently only creates columns, and any primary keys.
Tested on version 1.1.14
Add to your preferred folder for using gii generators or just put the "migration" folder in "protected/gii" ("application.gii" path alias) which is the default location for gii.
Ensure Gii is enabled in your configuration!
