 * \brief Store and load simulation attribute configuration

 *

 * While it is possible to generate a sample config file and lightly

 * edit it to change a couple of values, there are cases where this

 * process will not work because the same value on the same object

 * can appear multiple times in the same automatically-generated 

 * configuration file under different configuration paths.

 *

 * As such, the best way to use this class is to use it to generate

 * an initial configuration file, extract from that configuration

 * file only the strictly necessary elements, and move these minimal

 * elements to a new configuration file which can then safely

 * be edited. Another option is to use the ns3::GtkConfigStore class

 * which will allow you to edit the parameters and will generate 

 * configuration files where all the instances of the same parameter

 * are changed.
