[Rivet] MCT calculation in RIVET

[Simone Amoroso]

Hi Andy,

Thanks for looking into this.

As a short-term solution I can just link against the libraries, but it might be nice to find a way to have the code in rivet,
to avoid adding external requirements to run it.

cheers,
Simone

If the former, you can link analyses (either statically or dynamically) against extra libraries just by adding -L and -l flags to the end of the rivet-buildplugin command-line. To save you time while I work out what best to do with this thing...
