The
marple package is not yet updated to the new C++ interface.
It means that the present version of marple would not work correctly with
many-to-many relations. It could result in wrong output of matching
procedure. From other side the base function like prolongation or Kalman
formalism doesn't use this feature, so they should work as expected.
Anyway it is not recommended to use marple with the releases from
ARTE-02-04-r1 to ARTE-02-05-r3 (O.Igonkina).
