	/* The below function will list all folders and files within a directory
	It is a recursive function that uses a global array.  The global array was the easiest
	way for me to work with an array in a recursive function
	*This function has no limit on the number of levels down you can search.
	*The array structure was one that worked for me.
	ARGUMENTS:
	$startdir => specify the directory to start from; format: must end in a "/"
	$searchSubdirs => True/false; True if you want to search subdirectories
	$directoriesonly => True/false; True if you want to only return directories
	$maxlevel => "all" or a number; specifes the number of directories down that you want to search
	$level => integer; directory level that the function is currently searching
