I know enough about CIP to be dangerous.  I haven't gotten involved with
CIP-Motion yet, but it would be nice to have it availble in Wireshark by then. 
Besides learning about the CIP-Motion dissector gave me a few pointers on how
to improve other dissectors (ie CIP).

My biggest frustration is it seems each dissector I work with seems to have a
different whitespace rule.  I'd like to honor the "keep style as is", but
sometimes it goes unnoticed when developing if tab space value = # of spaces
used.  I'll fix it.

Wasn't sure if "public" variable or essentially recreating the value string was
the way to go (and have that "common" code (i.e. large macro) in packet-cip.h).
 In all likelihood they would remain the same.

I thought this was added at checkin time (automatically through SVN), and since
the dissector is new, wouldn't that fall on the developer doing checkin?
