This program resamples \file{instrument data}{instrument} to a given
\configClass{timeSeries}{timeSeriesType} using a resampling
\configClass{method}{interpolatorTimeSeriesType}.
This program can also be used to reduce the sampling of an instrument file,
but a better way to reduce the sampling of noisy data with regular sampling
is to use a low pass filter first with \program{InstrumentFilter} and then thin
out the data with \program{InstrumentReduceSampling}.
