the stopping variable will be interpolated
Arguments
data
Location data.
stopData
stopping variable data set.
Time.name
character naming time index variable in both data sets
interp
method of interpolation.
win

Details
Simply merges the data frames and interpolates based on the chosen method.
Both data frames have to use the same name for the time variable. Also
contains stopType which = "o" if observed or "p" for interpolated.
The merged data is truncated to the first and last time in the location data
set. Missing values in the stopping variable data set can be interpolated by
replacing them with zeros (full movement) or first replacing with zeros then
using a moving average to smooth the data. Only the missing values are then
replace with this smoothed data. This allows a smooth transition to full
movement.
