[Rivet] analysis

[Andy Buckley]

We are planning to remove uses of this Boost assign list_of from the
next minor Rivet release because of the C++98/03/11 compatibility issues
while using it.

We'd like to move to requiring C++11, but aren't sure that this is an
option yet, both because of the build settings of the LHC experiments,
and because the system compiler on SLC6 isn't capable of many important
C++11 features. LCG and the experiments don't use the system compiler,
of course, but for what I think are largely accidental / cargo cult
reasons, there are many "vanilla" SLC6 systems in use, particularly by
theorists :-/
