-*   USAGE:
-*     browser:
-*         JSONfn.stringify(obj);
-*         JSONfn.parse(str[, date2obj]);
-*         JSONfn.clone(obj[, date2obj]);
-*
-*     nodejs:
-*       var JSONfn = require('path/to/json-fn');
-*       JSONfn.stringify(obj);
-*       JSONfn.parse(str[, date2obj]);
-*       JSONfn.clone(obj[, date2obj]);
-*
-*
-*     @obj      -  Object;
-*     @str      -  String, which is returned by JSONfn.stringify() function; 
-*     @date2obj - Boolean (optional); if true, date string in ISO8061 format
-*                 is converted into a Date object; otherwise, it is left as a String.
