/**
* Class WPDA_Simple_Form_Item
*
* Simple forms consist of items. Items correspond with table columns. Basically an item is generated for every
* table column in the base table. Class WPDA_Simple_Form_Item handles a database column as a standard text item.
*
* It's possible to add dummy columns. Values for dummy columns however are lost when data is saved.
*
* Check out {@see WPDA_Simple_Form} to see how to use simple form items.
