creating this as a placeholder for implementing the two unimplemented options
for the moving window functions:  SamplePoints which applies the window length
against a non-uniform  grid, and nanflag, which allows it to include/exclude
NaN elements.  

both have been implemented in the moving function options for `fillmissing` in
the statistics package, but the base functions are rather different so it may
not be straightforward to port into movfun.  SamplePoints creates the
possibility that each window may include a different number of points, and
nanflag creates a possibility that each column includes a different number of
points. so right away they create issues with efficient parallel operation.
