included functions:
	[top level]
	- display(target/optional/)			- writes flash code to page
	- remove()							- removes flash code from page
	
	[editing]
	- edit(name,value) or edit(object) 	- edit flash settings
	- addVars("pet","dog")				- basic way to send a variable in to the flash file
	- setTarget(id of target div) 		- basic way to set the flash display location
	- setNoFlashMessage(message)		- Change content to be displayed if flash wasn't found
	
	[internal]
	- trace(true|false/optional/)		- (false) displays an alert dialog with the HTML code or (true) displays all possable settings for the flashBox
	- buildHTMLcode()					- returns the HTML code for the flashBox
	- showAllSettings()					- returns all possable settings for the flashBox

* I developed this code while learning javascript, but I'm sure there are similar flash codes out there. Use this freely if you like it.
	- This Script utilizes "MM_findObj()//v4.01" from Adobe as the $O function
	- This Script utilizes "AC_OETags.js" from Adobe to detect at least Flash Player 8
