+ * The class can also handle json-files and XML-files. The json input file might
+ * look like the following for the previous example:
+ *   @code
+ *     {
+ *       "Nonlinear solver" : {
+ *         "Nonlinear method" : "Gradient",
+ *         "Linear solver" : {

+ *         }
+ *       }
+ *     }
+ *   @endcode
+ * The advantage of using json-files is that this format is natively supported
+ * by Python, simplifying the running of paramter studies tremendously.
