+ *
+ * This method performs the second step (computation of remapping matrix) which may be CPU-time consuming. This phase is also the most critical (where the most tricky algorithm) in the remapping process.
+ * Strictly speaking to perform the computation of the remapping matrix the field templates source-side and target-side is required (which is the case of MEDCouplingRemapper::prepareEx).
