merge

If the seismogram server is returning multiple continuous seismograms for a request, this will join them into a single seismogram. Continuous means that the begin time of the second seismogram is approximately one sample period after the end time of the first seismogram. This processor does not merge overlapping seismograms or seismograms where there is a gap larger than one sample period. For those cases see collapseOverlaps and gapFill respectively.
