[Rivet] Rivet 1.2.2 release soon (this week?)

[Frank Siegert]

Hi Andy,

good idea, thanks for pushing :)

I was planning to improve the writing-an-analysis experience for a first 
time user a bit, and saw that you already did a major overhaul of the 
WritingAnAnalysis page, thanks for that!

In that context I had two thoughts:

1. Should we get rid of the plugindemo directory in favour of the new 
properly documented rivet-mkanalysis and rivet-buildplugin?

2. Should rivet-mkanalysis get an *option* to write the metadata into 
the C++ file (like it's done now in plugindemo)? For plugin analyses 
this might be useful to avoid having to edit more than one file (ok, the 
.plot file, but that comes at the very end and is optional).
It will also allow to use the plugin analysis with only 
RIVET_ANALYSIS_PATH set... at least I can never remember which other 
paths (RIVET_DATA_PATH, RIVET_INFO_PATH, ...?) I have to set.

Cheers,
Frank
