			To add a new "user friendly " directory name use the following syntax:
			objurl['actual_directory_name'] = 'Name You Want to Appear in Bread Crumb Trail';
			If a name is not provided then the actual directory name will be used with first
			letter capitalized. So for the example above the following strinf would print if
			a name was not defined: "Actual_directory_name". Please define all new names below
			with the existing names.
