  // For an interactionBlock (diagonal or extra diagonal) corresponding to
  // an Interaction, we need to know the position of its first
  // element in the full-matrix M. This position depends on the
  // previous interactionBlocks sizes.
  //
  // Note FP: at the time positions are saved in the Interaction
  // but this is wrong (I think) since it prevents the inter
  // to be present in several different osns.
  //

  // Computes real size of the current matrix = sum of the dim. of all
  // Interactionin indexSet
