      * Sometimes we need to parse a string with key-value pairs into 
      * a Properties object for later use. 
      * For example: 
      *     s = "a=1, b=2, c=3";
      * Instead of using "split" method, we can parse this easily 
      * with the Properties load method.
      * A piece of testing source code is listed as the following:
      *    
      *             String s= "a=1, b=2, c=3";
      *             Properties properties = parseStringToProperties(s, ',');
      *             System.out.println(properties.getProperty("a"));
