json: correctly treat multidimensional arrays of objects
json: correctly treat multidimensional arrays of objects

Multi-dimensional JSON array will be created for the members like

     std::string  fArr3[3][4][5];

In JavaScript one can use:

      var obj = JSROOT.parse(json_str);
      console.log('Array item', obj.fArr[1][2][3]);
