<p>A renderer for <code>UICollectionView</code>.</p>
<p>By providing a complete description of your view state using an array of <code><a href="../Structs/TableSection.html">TableSection</a></code>. <code>FunctionalCollectionData</code> compares it with the previous render call to insert, update, and remove everything that have changed. This massively simplifies state management of complex UI.</p>
