+		/* Escapes all the backslashes which are not translated correctly in the Flash -> JavaScript Interface
+		 * 
+		 * These functions had to be developed because the ExternalInterface has a bug that simply places the
+		 * value a string in quotes (except for a " which is escaped) in a JavaScript string literal which
+		 * is executed by the browser.  These often results in improperly escaped string literals if your
+		 * input string has any backslash characters. For example the string:
+		 * 		"c:\Program Files\uploadtools\"
+		 * is placed in a string literal (with quotes escaped) and becomes:
+		 * 		var __flash__temp = "\"c:\Program Files\uploadtools\\"";
+		 * This statement will cause errors when executed by the JavaScript interpreter:
+		 * 	1) The first \" is succesfully transformed to a "
+		 *  2) \P is translated to P and the \ is lost
+		 *  3) \u is interpreted as a unicode character and causes an error in IE
+		 *  4) \\ is translated to \
+		 *  5) leaving an unescaped " which causes an error
+		 * 
+		 * I fixed this by escaping \ characters in all outgoing strings.  The above escaped string becomes:
+		 * 		var __flash__temp = "\"c:\\Program Files\\uploadtools\\\"";
+		 * which contains the correct string literal.
+		 * 
+		 * Note: The "var __flash__temp = " portion of the example is part of the ExternalInterface not part of
+		 * my escaping routine.
