I was curious, so I did an implementation of 'sumskipnan' using the
approach above. The result is somewhat slower, but it supports
everything that 'sum' supports (complex matrices, Nd matrices). I'm
attaching the function in case people are interested. Should we replace
the current implementation with my m-file implementation? I don't use
the function, so I don't have any strong feelings here.
