CSDVP model re-implementation

CSDVP model needs to be reimplemented from JAVA to C++ (in a better and more robust way).

What must be kept

All the CSDVP model must from the JAVA implementation must be kept. However, the code must be structured to foresee a standaridation both of compentecy and course modelisation.

For example,

    public static int [][][] KNOWLEDGE_PER_COURSE = { //Express K as cpl, e.g. {1,35} -> 1st course { {1,50}, {4,20} }
            EMPTY_COURSE_KNOWLEDGE,
            { {1,75}, {4,50} }, //course 1's knowledge
            { {3,50}, {1,25}, {4,50} },
            { {0,50}, {2,50}, {5,25} },
            { {5,50} },
            { {1,35}, {2,25}, {5,5} },
            { {6,40}, {3,45}, {1,10} },
            { {0,25}, {2,40} }
    };

Need to be rewrite in C++ class.
