[Click] ICMPRewriter

[Coy Eleanor-B10245]

I'm trying to figure out how to code the ICMPRewriter for a simple NPAT
router. According to the documentation, it checks "MAPS, a space
separated list of IPRewriter-like elements to see how to rewrite." The
only example I could find, thomer-nat.click, uses an instance of
IPRewriter and an instance of ICMPPingRewriter as inputs to
ICMPRewriter. I assume the example is correct?
