<p>Creates sequences of messages based on various rules.</p>
<h3>Details</h3>
<p>There are three modes for creating message sequences:</p>
<dl>
<dt>Number of messages</dt>
<dd>groups messages into sequences of a given length. The <b>overlap</b>
option specifies how many messages at the end of one sequence should be
repeated at the start of the next sequence.</dd>
<dt>Time interval</dt>
<dd>groups messages that arrive within the specified interval. If no messages
arrive within the interval, the node can optionally send on an empty message.</dd>
<dt>Concatenate Sequences</dt>
<dd>creates a message sequence by concatenating incoming sequences. Each message
must have a <code>msg.topic</code> property and a <code>msg.parts</code> property
identifying its sequence. The node is configured with a list of <code>topic</code>
values to identify the order sequences are concatenated.
</dd>
</dd>
</dl>
<h4>Storing messages</h4>
<p>This node will buffer messages internally in order to work across sequences. The
runtime setting <code>nodeMessageBufferMaxLength</code> can be used to limit how many messages nodes
will buffer.</p>
