CodeThatTab is an advanced JavaScript tab control (page control) that
fully mimics look and the functionality of the tab control found in
Windows GUI specifications and serves the same purpose. Use CodeThatTab
to create a multiple page form within the same window. CodeThatTab
displays multiple overlapping pages that hold various content. The user
selects a page by clicking the page's tab that appears at the top of the
control (or in the other configured position).
