I added a possibility to select symmetric (around zero) cut
on energy in a cell when cluster energy is determined in
the reconstruction. This mode can selected by placing nonzero
value in column 1 row 9 of FN1P bank in NDB (GIPar(9) in the
FNCREC). This will only affect cluster energy and cell set
which belong to a cluster. Coordinates and estimators are
unaffected. For the moment the default nonsymmetric cut mode
will be used. Changes will be included in next H1REC release.
