+ * \a types and \a slicPerTyp. This method allows to load from a mesh (typically huge) in a MED file a part of cells of that mesh.
+ * The part of cells is specified using triplet (start,stop,step) for each geometric type. Only nodes lying on selected cells will be loaded to reduce
+ * at most the memory consumtion.

+ * \param [in] fileName - the name of the file.
+ * \param [in] mName - the name of the mesh to be read.
+ * \param [in] types - the list of the geo types of which some part will be taken. A geometric type in \a types must appear only once at most.
+ * \param [in] slicPerType - an array of size 3 times larger than \a types that specifies for each type in \a types (in the same order) resp the start, the stop and the step.
+ * \param [in] dt - the iteration, that is to say the first element of the pair that locates the asked time step.
+ * \param [in] it - the order, that is to say the second element of the pair that locates the asked time step.
