[Ifeffit] Ifeffit 1.2.2

[Matt Newville]

Hi Everyone,

I've just posted version 1.2.2 of Ifeffit.  This is mostly a bug-fix
release, and the core library has no new functionality. The major
improvements are that 1) 'reff' now works well in all path parametr
definitions and 2) feffit() fits in k-space correctly include the
k-weighting.  The build procedure from sources for linux and Mac OS
X are also slightly better.  More details on the changes to the core
library are below.

The windows installer includes the latest versions of athena,
artemis, and sixpack, each of which has several improvements.  
Thanks to Bruce and Sam for getting this release together!

Let me know if there are any questions or problems.
Thanks,

--Matt

Changes from v. 1.2.1:
	bugs:
	- fixed error with k-space feffit() fitting so that 
          k-weighting is now really used!!

	- fixed error with using reff in defined math expressions

	- increased size of math expressions to 256 operations/values.

	- changed restraint mechanism to work slightly better with 
	  multiple data	sets

	- fixed error in read_data() that allowed core-dumps when 
	  reading files larger than the maximum array size.

	build improvements:

	- switched configure to use autoconf 2.53, including 'newer'
	  automated searches for fortran libraries, setting default f77
	  compiler to g77, which should help builds on Mac OS X.
	
	- removed fortran subdirectory -- an existing, working fortran 
	  compiler is needed to build ifeffit.
	
	- fixed iconf_pgplot to check that PGPLOT directories listed
	  in the PGPLOT make really exist (and are directories) before
	  including them in the link arguments.

        - upgraded to readline 4.3

        - upgraded python installation to use Pmw 1.1
