.H 1 "Add the output from multiple inputs"

The `Add' node sums inputs from any number of nodes
to generate a single output stream. All inputs and the output must
have the same number of words per sample or `ElementSize'. For example
they must all be real or all complex. A check for overflow is made
for each addition. At overflow the output is forced to the largest legal
magnitude. The number of overflows is periodically reported.
The input can be scaled by a uniform factor before the overflow check.
