The  <font color=red>vstring categories = { ... }</font>
parameter lists the set of ID's that may be configured 
specially with regards to limits of how many of each id 
will be treated to be a given destination.  The message ID
is the string placed as the argument of edm::LogError(<font colr=red>"ID"</a>)
or the other message-issuing functions.
<p>
This is a <em>vstring</em> parameter, so the ID's are comma-separated.
<a>
For each destination, any or all of the categories listed may be used as
a PSet name, to establish limits and timescales for that destination reacting 
to messages of that type.
