The <font color=red>PSet default = { ... }</font> parameter, inside the context of a given destination,
specifies that for all types of messages <em>other than those explicitly dealt with by their own 
Pset's in this destination</em>, there should be a given limit on number of times this destination
will report messages of the same ID.
<p>
For example, having been assigned a default limit of 10 occurrences and timespan of 180 seconds, 
critical.txt would report the first 10 occurrences of a edm::LogError("thisID") message, and the first
10 occurrences of a edm::LogError("thatID") message.  After the 10 occurrences, an exponential backoff
kicks in.  After 180 seconds of no messages of that type, the count is reset, so that 10 more occurrences
could appear.

<p>
The <font color=red>PSet default = { ... }</font> parameter is optional.  If neither a default limit nor
a limit specific to the particular message ID is provided, then that destination will report all messages
of that ID.
