Azara 2.7 changes

0. Notable changes from 15 Nov 2001 release to 30 Oct 2002 release

0.01 process : added lp_extend

	Another new LP routine has been added, lp_extend,
	which does both forward and backward prediction
	using the so-called forward-backward algorithm.
	This uses complex SVD whereas the previous
	algorithms use only real SVD so this algorithm
	is recommended for complex data.

0.02 plot2 : added new module fit

	A new module, accessible from the peaks module,
	allows fitting of (e.g. decaying) peak intensities
	for families of peaks.

0.03 connect : allow more heavy atom types

	In addition to carbon and nitrogen, now any atom type which
	is not hydrogen is considered to be a heavy atom.  A warning
	is given for atom types other than hydrogen, nitrogen,
	carbon, oxygen and sulfur.

0.04 connect : change specification of unknown shift

	An unknown shift was specified to be equal to -99 but this
	is now changed to be any shift which is less than or equal
	to -99.

0.05 connect : allow multiple residue ranges

	For a given columns it is now possible to have multiple
	ranges specified, in which case shifts are accepted if and
	only if the residue lies in one of the ranges.

0.06 plot2 : put in file selection dialogue

	In the extract module it is now possible to choose the
	parameter file with a file selection dialogue.

0.07 plot2 : allow multiple peak selection

	In the peaks module it is now possible to select (and
	hence delete) multiple peaks at once.

0.08 project: allow threshold

	For projection it is now possible to specify a threshold
	below which (in absolute value) a value is not summed.
	This might help prevent negative baselines eliminating
	positive signal.

0.09 connect: allow output of null matches

	It is now possible to output crosspeaks which do not
	have any matches to a separate file.

0.10 viewer: new program

	There is now a program which will let you view contour
	files created by the contours program, with very basic
	functionality.

0.11 components: new program

	There is now a program which calculates the principal
	components of a group of spectra.
