	* arts-2-1-755

	* src/methods.cc (scat_meta_arrayAddTmatrix):
	Updated GIN and description due to the changes for the aspect
	ratio and size inputs.
	Numeric aspect_ratio --> Vector aspect_ratio_grid
	Vector diameter_grid --> Vector diameter_max_grid

	* src/workspace.cc (scat_meta):
	Corrected two errors in the description.

	* src/m_tmatrix.cc (scat_meta_arrayAddTmatrix):
	Changed size input from equivalent diameter to diameter_max
	and changed the aspect ratio from Numeric to Vector. Added a
	loop to calculate meta data for each combination of diameter_max
	and aspect_ratio. 
	Before the diameter_max was calculated, now it's the volume
	that is calculated from diameter_max and aspect_ratio.

	* src/m_cloudbox.cc (pnd_fieldSetup):
	Added a new PND parametrization with an included shape
	distribution (H13Shape).

	* src/cloudbox.cc: 
	(pnd_fieldMH97, pnd_fieldH11, pnd_fieldH13):
	Added a check to make sure that just one aspect ratio is used
	for these parametrizations, just as before.

	(pnd_fieldH13Shape):
	The new PND parametrization with an included shape
	distribution (H13Shape).

	(IWCtopnd_H13Shape, area_ratioH13):
	The actual parametrizations containing the equations and
	variables to calculate the PND and area ratio based on temperature.

	* src/cloudbox.h:
	(pnd_fieldH13Shape, IWCtopnd_H13Shape, area_ratioH13):
	The same parametrizations have been added as in 
	src/cloudbox.cc.

	* controlfiles/artscomponents/tmatrix/TestTMatrixSSD.arts:
	Updated due to the changed inputs (diameter_max_grid and
	aspect_ratio_grid)
