In terms of behavior, this is an alternative to filter() for a moving-average kernel. The running time does not grow with filter length beyond N=500.

The code uses a variant of the cumsum-trick, although not the "garden variety" but in a way that does not run into numerical issues for long data arrays.

The function is suitable for incremental (online) processing.

1.2.0.0

The N<500 case is now correctly implemented... (had a dumb error before)

1.1.0.0

Fixed an issue pointed out by Jan Simon (failed to determine along which dimension to filter when the signal was a scalar) and updated the docs.
