// I prefer to use the ParameterHandler class in a slightly different way than
// usual: The class Parameters creates, uses, and then destroys a
// ParameterHandler inside the <code>read_parameter_file</code> method instead
// of keeping it around. This is nice because now all of the run time
// parameters are contained in a simple class and it can be copied or passed
// around very easily.
