/* 
 * A jQuery plugin by Brian Holt that will search the selected blocks for 
 * specially-defined footnote elements.	 If found, these elements will be 
 * moved to a footnotes section and links to and from the footnotes will 
 * be created.
 *
 * See http://www.planetholt.com/articles/jQuery-Footnotes	
 * for full documentation.
 *
 * By default, footnotes will be found in SPANs with the footnote class,
 * and in BLOCKQUOTEs with a TITLE attribute.
 *
 * Thanks to CSSNewbies.com for the general idea, which I have enhanced 
 * and implemented with as a jQuery plugin.
