 * Beginning of research about drag'n'drop user experience
 * using Jquery & Jquery UI
 *
 * 6 steps for the moment:
 * - find the draggable object with mouse reaction
 * - transform the object to a little clone (easier move)
 * - the drop zone is highlighting
 * - this zone valid the transfer with the clone
 * - ...and accept the clone
 * - the clone disappear
 *
 * every messages are usefull notification
