<h2>Demonstrates:</h2>
<ul>
<li>
Fully dynamic and interactive multi-level grouping with filtering and aggregates over <b>50'000</b> items<br>
Each grouping level can have its own aggregates (over child rows, child groups, or all descendant rows).<br>
Personally, this is just the coolest slickest thing I've ever seen done with DHTML grids!
