 *
 * As of now (Aug. 16, 2006) the plugin has been written with the 1.0.1 release of jQuery (rev 249) which
 * is available from http://jquery.com/src/jquery-1.0.1.js
 *
 * A note regarding rgb() syntax: I noticed that most browsers implement rgb syntax as either an integer 
 * (0-255) or percentage (0-100%) value for each field, that is, rgb(i/p,i/p,i/p); however, the W3C 
 * standard clearly defines it as "either three integer values or three percentage values" [http://www.w3.org/TR/CSS21/syndata.html] 
 * which I choose to follow despite the error redundancy of the typical behaviour browsers employ.
 *
 * Changelog:
 *
 *    0.7:
 *        - Added the awesome custom attribute support written by George Adamson (slightly modified)
 *        - Removed bgColor plugin dependency seeing as attr is customizable now...
 *    0.6:
 *        - Abstracted getBGColor into its own plugin with optional test and data retrieval functions
 *        - Converted all $ references to jQuery references as John's code seems to be shifting away
 *          from that and I don't want to have to update this for a long time.
 *    0.5:
 *        - Added simple argument syntax for only specifying start colour of event
 *        - Removed old style argument syntax
 *        - Added 'interval', 'final, and 'end' properties
 *        - Renamed 'color' property to 'start'
 *        - Added second argument to $.highlightFade.getBGColor to bypass the e.highlighting check
 *    0.4:
 *        - Added rgb(%,%,%) color syntax
 *    0.3:
 *        - Fixed bug when event was called while parent was also running event corrupting the
 *          the background colour of the child
 *    0.2:
 *        - Fixed bug where an unspecified onComplete function made the page throw continuous errors
 *        - Fixed bug where multiple events on the same element would speed each subsequent event
 *    0.1:
 *        - Initial Release
 * 
 * @author          Blair Mitchelmore (blair@offput.ca)
 * @version         0.5
 
 
 *  PhotoSmash note...I've renamed functions to bwbpsFade to avoid namespace clashes
