+ * \brief A field template can be seen as a field without the array of values.
+ *
+ * A field template aggregates a MEDCouplingMesh and a spatial discretization object (instance of
+ * MEDCouplingFieldDiscretization).
+ *
+ * MEDCouplingFieldTemplate is the most appropriate type for the preparation of matrix using
+ * MEDCouplingRemapper::prepareEx, since it contains the minimal information requireds to prepare
+ * the interpolation matrix.
