I have some functions that currently operate on a vector of data.
I would like to convert these to moving window functions.

eg.
Like sum that adds the total value of a vector.
and msum that gives the sum within a moving window.

I would like to be able to take a function f[v]. and do window[f;window;v] to have that function applied over moving windows of v.

Am I clear in my explanation?
and can anyone suggest the best way to do this?
