+ * Short
+ * 
+ * 3. {Category} define a category for the Function. it is required. its value is user-defined .
+ * 
+ * 4. {param} 's format is: {param} <type>[(<default value or closed list values>)] <name>[ : <comment>]
+ * 
+ * <type> 's value should be one of: string, int, list, double, object, boolean, long, char, date. <name>'s value is the
