	* pyatmlab-0-0-56

	* pyatmlab/collocations.py(CollocationDescriber):

	- Fig bug with regridding.  No need to "remove data above range".  I'm
	going to interpolate on the new grid *anyway*.  Removing just risks
	removing too much and extrapolating where there is no need.  It's
	extrapolation I want to avoid, the way to do this is to set the target
	grid (from z_xh) small enough and not to remove data wherever I'm
	above lowest_z_max.

	- Write out all DOFs to get a histogram with pgfplots

	- Move get_shared_range into its own routine.  I might have to look at
	lower limits as well.

	* pyatmlab/datasets.py(EurekaHDF):

	- Remove workaround for reading PEARL HDF4 file, after bugfix in
	Python-hdf4.

	* pyatmlab/math.py:

	(linear_interpolation_matrix):

	- Oops, W was turned around.  Fixed.

	(regrid_ak):

	- Don't mess with the new grid.  Only with the old.
