+ * jsPlumb
+ *
+ * Title:jsPlumb 1.7.0
+ *
+ * Provides a way to visually connect elements on an HTML page, using SVG or VML.
+ *
+ * This file contains the base class for library adapters. From 1.7.0 onwards all event management internal to jsPlumb is handled
+ * through Mottle, regardless of the underlying library. Dragging - and the events associated with it - is still handled
+ * by the library.
