0016  * Author M. De Mattia - 16/11/2009
0017  *
0018  * Simple class used to store configuration values. <br>
0019  * It stores a map<std::string, std::string> with all the parameters and their values. <br>
0020  * The put and get methods are provided to store and access the parameters. <br>
0021  * The put method retuns a bool which is true if the insertion was successuful. If the parameter
0022  * is already existing the insertion will not happen and the return value will be false. <br>
0023  * The get method is templated and works like the getParameter<type> of the framework. <br>
0024  * The isParameter method can be used to check whether a parameter exists. It will return a
0025  * bool with the result. <br>
0026  * The printSummary and printDebug method return both the full list of parameters. <br>
