An extra check on the timestamp has been added in SMETIO in order to throw an exception for duplicated timestamps or non chronological order (as happens with daylight saving time). Some private methods in libinterpol2D as well as some () operators for the arrays are now inline in order to help autovectorization find more potentially vectorizable code (and it finds some more). An arithmetic exception could happen in FilterRate (division by 0) and has been fixed.
