		PROTOTYPING SECTION. PUT ALL PROTOTYPES HERE FOR EASY LOCATION
		The problem with this is that prototypes can only be used in this file, and on a page "including" this
		script. We can't use them on other files because they can't have include files and we don't want inter
		javascript file dependency. Redefining them is OK though, so could have these prototypes in more than one
		javascript file and if you included both of them, the last one's definitions would apply and there isn't a
		runtime error associated with the redefinition. The redefinitions just shouldn't be different change from 
		file to file, otherwise the changed version would break code depending on another version. dan kahle
