This function pushes onto the stack a kernel smoothing mapper using a silverman kernel. The mapper applies the Nadaraya-Watson kernel-weighted average algorithm.

The function expects on top of the stack a bandwidth expressed as an odd number of ticks and below it a step expressed in time units. The step parameter is used to determine the distance of a tick from the tick being computed to feed it into the kernel. The bandwidth in time units is the bandwidth in ticks times the step.
