Cleanup of stats, killed the initialize and allocated and initialize
pointers at NULL
First test with filter split stats
Remove the error checks in attribute addition in stats, because they
return true and mess up the error count. Framework for stats seems
to be working now.
One step further, calculated filters
Working test case with filtered means
Typo in long name stats variable
Add filter version of the 2nd order flux calculation
Switch the default filter point to the half levels
Added profiles for the filter area at the half levels
Filters accurate up to machine precision again, forgot one interpolation
Ql filter, thusfar
Use the NC_FILL_VALUE in stats if the filtercount is equal to zero, this
allows tools that respect the FillValue attribute to handle the data
much better. Matplotlib can make the proper averaging profs now.
Improve plotting script for BOMEX to use all filters
Forgot to calculate the fields in the tmp arrays
Added the buoyancy to the stats
Give user control of line color and styles
Added a DNS sea-breeze case
