Each file builds the library incrementally. datatable-beta.js also
assumes that the YAHOO global is in place, for example. yahoo-min.js
or yahoo-dom-event.js or utilities.js must therefore come before
DataTable includes a class that extends YAHOO.util.DDProxy in
dragdrop.js to facilitate the column DnD. That class must be known
before datatable-beta.js can extend it.
