async incarnation of fold.
async incarnation of fold. Fold return future, which successed when channel is closed.
Operations withing fold applyed on result on each other, starting with s0.
val fsum = ch.afold(0){ (s, n) => s+n }
Here in fsum will be future with value: sum of all elements in channel until one has been closed.
