Changelog. A lot less detailed than usual, at least for past
history. 



2003/09/30: Added LOC_TO_GLOB and GLOB_TO_LOC support routines. 

2003/09/30: Changed interface for smart update capabilities: choose
	    with optional parameters in ASB routines. 

2003/09/16: IFC 7.0 had a strange behaviour in the test programs:
	    sometimes the declaration of PARTS dummy argument with an
	    INTERFACE would not work, requiring an EXTERNAL
	    declaration. The proper INTERFACE works now with 7.1.

2003/03/10: Halo data exchange in F90_PSHALO can now be applied to
	    integer data; create appropriate support routines. 

2002/12/05: Initial version of Fileread sample programs.

2002/11/19: Fixes for JAD preconditioner.

2002/11/19: Methods for patterns: create a  descriptor without a
	    matrix. 

2001/11/16: Reviewed the interfaces: in the tools section we really
	    need the POINTER attribute for dense vectors, but not in
	    the computational routines; taking it  out allows more
	    flexibility. 

2001/09/16: Smart update capabilities.

2001/03/16: Renumbering routines.

2001/01/14: Added extensions to compute multiple DOTs and AMAXs at once;
