Last change on this file since 2821 was 2821, checked in by gkronber, 14 years ago

Removed access to local variable DIFFERENTIALS_ALLOWED in time series prognosis engines. #877 (Predefined GP engines for time series prognosis are defect because of the removal of local variables of function library injectors in #748)
