 *  @changeLog_________________________________________________________________________________
 *  
 *  Nov  15th 2008
 *  JJJ - incremented version to 0.68.3
 *  	- Fixed bug which occured when ol was used instead of ul.. was because you cannot use selectors such 
 *  		as 'ul, ol' with getParent() and getNext() despite the mootool documentation saying "if Selectors 
 *  		is included, a full CSS selector can be passed."
 *  
 *  Nov 4th 2008
 *  JJJ - incremented version to 0.68.2
 *  	- Removed extranious comma which threw an error in IE. (Thanks to Robert S. for catching that)
 *  	- Added check to change the opacity to 99.9 if it is over 99 due to the fact that 
 *  		setting the opaicty to 100% in safari caused misc strange behaviour (thanks to Roland Barker 
 *  		at xnau webdesign for reporting this one)
 *  
 *  Nov 3rd 2008
 *  JJJ - Renamed menuWidth option to stretchMainMenu and made it work much quicker
 *  
 *  Nov 2nd 2008
 *  JJJ - Finished adding several callback functions
 *  	- Added fixHasLayoutBug option
 *  
 *  Oct 4th 2008
 *  JJJ - Continued to go through code to optimize and clean it up
 *  	- Added center option
 *  
 *  Sept 28th 2008
 *  JJJ - Incremented version to 0.68
 *  	- Began optimizing & better commenting code
 *  
 *  Sept 16th 2008
 *  JJJ - Incremented version to 0.67
 *  	- Specifically set each submenu z-index on show, incrementing each time. Set z-index back to 1 on hide.
 *  
 *  Sept 14th 2008
 *  JJJ - Added bottom edge detection and redirection (if bottom of subsequent submenu is lower than the scrollheight of the body)
 *  
 *  Sept 10th 2008
 *  JJJ - Did a google search for MooMenu and it looks like that name is already being used, so I must reluctently change the name.
 *  		The name I have chose to move forward with is: MenuMatic.
 *  
 *  Sept 8th 2008
 *  JJJ - Incremented version to 0.66
 *  	- Fixed IE bug whiched caused some events to be incorrectly attached to parent buttons causing sub submenus to not open
 *  	  correctly when transitions are enabled. This error was introduced in 0.65. 
 *  
 *  August 10th 2008
 *  JJJ - Incremented verion to 0.65
 *  	- Fixed bug with edge detection and redirection
 *  	- Improved javascript and CSS to assure the submenus will always be on top
 *  	- Improved edge detection and redirection logic
 *  	- Added subMenusContainerId option so that if you have multiple MooMenu instances on a page they can be styled differently
 *  
 *  May 7th 2008
 *  JJJ - Incremented version to 0.64
 *  	- Fixed bug with that occured when firing events
 *  
 *  April 28th 2008:
 *  JJJ - Incremented version to 0.63
 *  	- Added killDivider option
 *  	- Removed focus on hover since it adds browser default dotted outline
 *  	- Changed menuWidth option to use actual width of nav element (so it can be set in css) instead of a width set in javascript
 *  
 *  Feb 17th 2008:
 *  JJJ - Incremented version to 0.62
 *  	- Added mmbClassName and mmbFocusedClassName options to allow morphing of main menu btns
 *  
 *  Feb 16th 2008:
 *  JJJ - Incremented version to 0.61
 *  	- Made changes to options syntax. 
 *  	- Improved keyboard accessability to take into account a menu's orientation, and its x and y direction when using arrow keys
 *  	- Added matchWidthMode option.
 *  
 *  Feb 14th 2008:
 *  JJJ - Incremented version to 0.60
 *  	- Added menuWidth option to simulate a table based layout for the main menu when the orienation is horizontal
