Add a Lookup Column Assistant
Lookup Column Wizard allows you to add a database relation for a single column. Basically, once such relation is defined (one-to-many), it allows user to select one of many values for a given field using some sort of combo box. The task is to deliver intelligent GUI for this wizard. This task doesn't include a code for column creation.
