The <font color=red>vstring destinations = </font> {"detailedInfo.txt", ... }
parameter establishes one or more file (or ostream) destinations for the 
messages issued.  The destinations can be configured individually to establish
filtering of messages.  Since this is a <em> vstring</em> parameter, the 
names of the destinations are separated by commas.
<p>
In this case, we have specified four files (perhaps overkill in ordinary
circumstances, but we wished to use the four illustrate various configuration 
options).  We have also specified both cerr and cout; if this is done,
it is recommended that cout be re-directed to a file, otherwise the message
contents will be inter-mixed with those sent to cerr.
<p>
If messages are issued prior to the initiation of the MessageLogger service,
the configuration of these destinations will not yet have occurred.  Such
messages will be sent to cerr alone.
