- as of 1248: implemented in branches/ohl/omega-development/cross_flavor_cse
- compiles, needs testing before merging with trunk

Implemented CSE across flavors in r1250
- tested with various final state flavor sums
- the process g, g -> g, u:d:s:c:b, U:D:S:C:B runs faster by a factor 2.5

As pointed out by WK, my tests where not comprehensive and wavefunctions are not uniquely defined my flavor and momentum (e.g. A(u,ubar) vs. A(d,dbar)
Reverted the merge in r1250

Implementation complete as of r1335. Needs testing and merging into the trunk.

Implemented CSE across flavors correctly in r1340
(svn merge -r1229:1335 svn+ssh://login.hepforge.org/hepforge/svn/whizard/branches/ohl/omega-development/cross_flavor_cse)
make check works within statistical errors, color tests are passed with higher statistics and cuts to get better convergence.
