dupfilter_exact(sdata)

This is a partial component of dupfilter
, although works as a stand-alone function.
It looks for temporally and spatially exact locations and retains only a single fix (latitude/longitude pair) per time and location.
The input data frame is returned with temporally and spatially exact duplicates removed.
