[Rivet] compiling an analysis

[Sercan Sen]

Hi Frank,

I create two new analysis test.cc and CAPTEST.cc and compile them. As  
far as I see, we need to name the analysis by using UPPER cases to  
avoid possible problems.

ssen> rivet --list-analyses
Rivet.AnalysisInfo: ERROR  Parse error when reading analysis data  
from ./test.info

Exiting, since this probably isn't intentional!

--------> CAPTEST analysis works but says not compatible with the  
input file. When I look at the CAPTEST.cc, I realized that

setBeams(PROTON, ANTIPROTON); (by default)

and I changed it to setBeams(PROTON, PROTON); which is compatible with  
my events.

And I change setNeedsCrossSection(true); to setNeedsCrossSection(false);

May I ignore Parse ERROR right now ? Do you think,  will parse error  
disappear when I edit CAPTEST.info ?

Thanks again
Sercan
