[Clas_hadron] Morrison abstract

Hi Brian:

Your statement that "...there are no previous measurements for double
polarization observables" desperately needs to be preceded by a
statement of exactly what process you're talking about.  CLAS has
published several double polarization observables in multiple reactions
over the years, as have (I suspect) several other facilities.  I would
suggest rewording the second sentence as

"In the eta photoproduction process on the proton, there are relatively
few single polarization measurements, compared to unpolarized
differential cross section measurements, and no double polarization
measurements."  Some wordsmithing is still needed there.

John
