A base WordPress database table class, which facilitates the creation of and schema changes to individual database tables.

This class is intended to be extended for each unique database table, including global multisite tables and users tables.

It exists to make managing database tables in WordPress as easy as possible.

Extending this class comes with several automatic benefits: - Activation hook makes it great for plugins - Tables store their versions in the database independently - Tables upgrade via independent upgrade abstract methods - Multisite friendly - site tables switch on "switch_blog" action
