[IDV #KDK-897162]: IDV 2.7 and HIRLAM hybrid files

Ernst,

atmosphere_hybrid_sigma_pressure_coordinate attribute was added to vertical 
pressure coordinate type variables. It uses the calculations described at:

http://www.ecmwf.int/research/ifsdocs/DYNAMICS/Chap2_Discretization4.html#961180

Your sample file HIRLAMhybrid.grib, the vertical pressure coordinates don't 
seem correct to me according to the above documentation. The test file 
ECMWF.2008.09.07.T00Z.uad_HGrbF00.A08334081908 was used, it had 91 levels and 
it follow the above documentation and the a and b values matched table located 
at:
http://www.ecmwf.int/products/data/technical/model_levels/model_def_91.html

The release with the fixes will be available sometime mid September.
