Output a received input token, unless the <i>inhibit</i> port receives a
token at the same time. If no token has been received on the <i>input</i>
port when a token is received on the <i>inhibit</i> port, then no output is
produced. The inputs can be of any token type, and the output
is constrained to be of a type at least that of the input.
<p>
Both the <i>input</i> port and the <i>output</i> port are multiports.
Generally, their widths should match. Otherwise, if the width of the
<i>input</i> is greater than
the width of the <i>output</i>, the extra input tokens will
not appear on any output, although they will be consumed from
the input port. If the width of the <i>output</i> is greater
than that of the <i>input</i>, then the last few
channels of the <i>output</i> will never emit tokens.
<p>
This actor is similar to the Sampler actor in that it modifies a
stream of events based on the presence or absence of events from another
input. This actor reacts to the absence of the other event, whereas
Sampler reacts to the presence of it.

The inhibit port, which has type Token. If this port
does not receive a token, then the most recent token from the
<i>input</i> port will be emitted on the <i>output</i> port.
