[Rivet] Using a projection "on the fly"

[Hendrik Hoeth]

Hi,

I'd like to use the Thrust projection with objects I define inside the
analyze() method, so this whole applyProjection business doesn't quite
apply here. Good news is: There are calc() methods which I can call
using a list of momenta. But first I need some kind of Thrust object.
How do I get there?
