Azara 1.0 changes

3. Notable changes from 04 Feb 1995 release to 22 May 1995 release

3.01 process : user determination of block size

	For nonblocked (sequential) data, the user can now set
	the block size, instead of letting the program do it.
	The 'par' file must have the keyword 'blocks' with the
	following syntax
	    blocks <block size, dim 1> ... <block size, dim #dim>
	This line must occur after the line with the 'ndim'
	keyword, and before any occurence of a line with the
	'dim' keyword.  There must be no occurence of the
	'block' keyword.  All of the block sizes must be
	greater than 0.  To be compatible with Ansig the
	product of the block sizes should be 4096.

3.02 contours : fixed contouring bug

	When restricting the number of points in any of the
	dimensions, using the keywords 'pnt_range' and/or
	'ppm_range', there are various tricky boundary
	conditions that need to be analysed, because the
	input data is blocked, and the boundary points
	defined by the range do not have to fall on the
	boundaries defined by the block.  There are two
	dimensions that are contoured, and in the first of
	these one of the boundary conditions was incorrectly
	implemented, thus instead of
		pointer += size_of_block
	the code should have been
		pointer += size_of_block - correction
	where the correction is zero except in the 
	exceptional boundary case.

3.03 process : commands in script files

	Script files can now have commands given in the file,
	rather than in separate (command) files, as was required.
	Thus the following syntax is now allowed in par files:

		script_com <dimension>
			[ commands ]
		end_script

	Similarly, maxent commands can now be given in a
	command file (for one-dimensional maxent) or in a
	script file, using the following syntax:

		maxent_com <dim>
			[ maxent commands ]
		end_maxent

	for one-dimensional maxent, or

		maxent2_com <dim 1> <dim 2>
			[ maxent commands ]
		end_maxent

	for two-dimensional maxent, or

		maxent3_com <dim 1> <dim 2> <dim 3>
			[ maxent commands ]
		end_maxent

	for three-dimensional maxent.
