	* pyatmlab/dataset.py(MultiFileDataset):

	- When I can't open the granule start times file, open a *copy* read
	only.  Opening the same one read only still doesn't work...

	* pyatmlab/datasets.py:

	(TansoFTSBase, TansoFTSv001, TansoFTSv10x):

	- Split these classes into different versions.

	* pyatmlab/math.py:

	(regrid_ak): Added function for regridding averaging kernel

	* pyatmlab/physics.py(p2z_hydrostatic):

	- WARNING: Comment out p0/z0-check; is this really needed?
	  This might introduce bugs, caution needed!  WARNING!
