**Note:** In many applications, measurements are taken with an instrument which
is towed behind, or pushed ahead of where the locations are recorded.
Use this function to estimate the actual location of the instrument.
The method determines the heading along the line, using a "thinned"
version of the line. The degree of thinning is based on the size of the
offset; the larger the offset, the greater the distance between sample
locations used to construct the thinned lined used for determining headings.
The thinned line is splined at a frequency greater than the sample
frequency, and the heading at any given point is determined from the
vector formed by the closest two points on the splined line. The
correction (behind, in front, left or right) is determined with respect
to the heading, and added to the original location.
IF this method fails, no dummies, no duplicated locations, no reversals
are produced.
The algorithm:
1. Determine average distance between each point = D
2. Smoothing interval = MAX(2*D, Offset distance) = I
3. Thin input points to be at least the smoothing interval I apart from each other.
4. Smoothly re-interpolate the thinned points at five times the
original average distance D.
5. For each input point, calculate the bearing using the nearest points
on the smoothed curve

The returned offset X, Y

Care should be taken when choosing the symbol size, because
if the point density is too high, all the points will get

**Note:** If the input VVs are not REAL, copies are made to
temporary REALs for processing.
If the window size is even, it is increased by 1 so that the
output value is put at the exact center index of the window.
Statistics are calculated on the values in a window
surrounding the individual data points.
By shrinking the window at the ends, one-sided effects can be
eliminated. For instance, if the data is linear to begin with,
a rolling mean will not alter the original data.
However, if the window size is kept constant, then values
near the ends tend to be pulled up or down.
With shrinking, the window is shrunk so that it always has the
same width on both sides of the data point under analysis;
at the end points the window width is 1, at the next point in
it is 3, and so on, until the full width is reached.
The median value is calculated by sorting the valid data in
the window, then selecting the middle value. If the number
of valid data points is even, then the average of the two
central values is returned.
The mode value is defined as the value which occurs most
frequently in the data. This value may not even exist, or
may not be unique. In this implementation, the following
algorithm is used: The valid data in the window is sorted
in ascending order. The number of occurrences of each data
value is tracked, and if it occurs more times than any
value, it becomes the modal value. If all
values are different, this procedure returns the smallest
value. If two or more values each have the same (maximum)
number of occurrences, then the smallest of these values is
returned.
