Azara 2.6 changes

0. Notable changes from 15 May 2001 release to 15 Nov 2001 release

0.01 connect : allowed atoms to be repeated

	In the input shift table atoms can be repeated, for a
	given peak only one match (if there is one) of these
	is output but all are counted in the match total.

0.02 plot2 : added comparison of peak shapes with different sf

	In the peaks module there is now an option to align the
	centers of peaks and scale the heights so that the
	peak line shapes can be compared even if the spectra were
	recorded on spectrometers with different spectrometer
	frequencies.  This is effectively giving peak line shapes
	in Hz but with peak centers in ppm.

0.03 all : allow reversal of meaning of swap in par file

	If FLIP_SWAP is defined when compiling par.c, i.e. in
	global makefile, then the meaning of what is swapped is
	reversed.

0.04 connect : residues check now done for assignments

	The check for residue number is now also done for assigned
	atoms.

0.05 all : lots of endianess possibilities

	Permitted keywords in par files now include 'big_endian'
	and 'little_endian', they specify the endianess of the data.
	Further, some options have been added in global makefile.
	If WRITE_ENDIAN is defined then endianess is written to
	output par file.
	If BIG_ENDIAN is defined then data is assumed to be big
	endian by default.
	If LITTLE_ENDIAN is defined then data is assumed to be
	little endian by default.

0.06 plot2 : fixed resizing bug

	In certain circumstances on the initial draw the pixmap
	was reallocated in the middle of the drawing because the
	resize callback was called.  This caused a crash because
	the old pixmap was freed. 

0.08 plot2 : changed loop parameters to floats and added loop2

	The loop first, end, step parameters have been changed to
	floats from ints.  An extra command, loop2, has been added
	which allows the number of decimals places to be used in
	the variable to be specified, the old loop command
	assumes 0.

0.09 process : added lp_forward and lp_backward

	Two new LP routines have been added, lp_foward, which
	should replace lp_last and lp_last2, and lp_backward,
	which should replace lp_first and lp_first2.
