Query methods
For user application: Following code are do NOT need to change. The reason can not put following functions in base class `AlpsParameterSet` is that `chrParams` and `endOfChrParams` etc., are NOT the same as those declared in base class. The members of the parameter set can be queried for using the overloaded entry() method. Using the example in the class documentation the user can get a parameter with the "<code>param.entry(USER_par::parameter_name)</code>" expression.
