      <description>
ExplicitIgnoredCatchBlock finds instances where an exception is caught,
but nothing is done.  In most circumstances, this swallows an exception
which should either be acted on or reported.  However if you want to
ignore this exception quietly, then state so by changing the catch
variable to 'ignore'
