[PD] Multi-dimensional arrays

[Tedb0t]

Thanks for the responses everyone; I've been using gridflow and after a rocky start I've figured out what seems to be a pretty efficient solution, based around [#store] and [#many].  I'll be putting the patch up online very soon!

But many GridFlow object-classes don't know what's a channel, and don't need to know. In any case, a single structure contains all channels, numbered. Thus it's easy to have any number of channels, even a million.
