[PD] saving arrays

[Miller Puckette]

Hi Greg,

I think the best way is to keep the arrays _outside_ the abstractions and
just have the abstractions refer to them by name.   Abstractions themselves
can't save internal "state"; two instances of the same abstraction are, by
design, identical except in their arguments.

It's also possible to save and restore arrays within abstractions manually,
but I think it's almost always better to have the calling patch own the 
data.

cheers
Miller
