[CM] fastest way to pass block of samples in and out of s7

[Iain Duncan]

Hi Bill, maybe I'm missing something obvious, but how do I access the data
in the vector wrapper from the Scheme side? Do I need to separately do some
FFI work to bind a symbol to it (ie. define it?)

Also, I notice in the ffi test example you follow creating those with calls
to s7_gc_protect, so presumably I should do that too eh?

thanks!
