+/**
+ * @file treegrid.min.js
+ *
+ * @brief
+ * TreeGrid is a visualization which represents data in a hierarchical grid
+ * view. It is designed to handle large amouts of data, and has options for lazy
+ * loading. Items in the TreeGrid can contain custom HTML code. Information in
+ * one item can be spread over multiple columns, and can have action buttons on
+ * the right.
+ * TreeGrid offers built in functionality to sort, arrange, and filter items.
+ *
+ * TreeGrid is part of the CHAP Links library.
+ *
+ * TreeGrid is tested on Firefox 3.6, Safari 5.0, Chrome 6.0, Opera 10.6, and
+ * Internet Explorer 9+.
