This actor selects from the channels on the
<i>input</i> port, copying the input from one channel to the output,
based on the most recently received value on the <i>select</i> input.
If the selected channel has no token, then no output is produced.
The <i>select</i> input is required to be an integer between 0 and
<i>n</i>-1, where <i>n</i> is the width of the <i>input</i> port.
If no token has been received on the <i>select</i> port, then null
is sent to the output. The <i>input</i> port may
receive Tokens of any type, but all channels must have the same type.
<p>
One token is consumed from each input channel that has a token.
Compare this with the Select actor, which only consumes a token on
the selected channel.
