speeding up ACCUMARRAY

I find it strange that no FEX contributors have tried to improve upon ACCUMARRAY, since I think it's widely agreed that it is slow.

I'm wondering if the reason ACCUMARRAY is so slow (despite being a built-in) is that it has to support so many different options, and whether a customized mex version, one which supported only summation accumulation, for example, could improve upon it.
