c4ae5f02f8 Changed fortran interface port to (hopefully) support CRAY fortran 
compilers and any other fortran compilers that mangle subroutine
names using all caps.

a500203e40 Removed the F90 prototypes from the header files because they aren't 
needed and don't make sense.

bf9189804b Conjugate gradient is now implemented by a file in the new directory krylov. 
The string "Struct" has been inserted into names of vector operations.

ad9a961eb7 Removed pthreads port of Struct codes (and PTHREADS_MANGLING stuff from 
Makefiles).  To be re-added later (possibly) in a cleaner form.
Added DOC++ reference comments to Struct '.h' files.
Changed names of Struct include and lib files.
Removed 'stencil' argument from interface for StructVectorCreate.

33ffbfb127 Rewrite of SparseMSG with local weighting to handle anisotropies. 
Not yet fully tested and debugged.

efb722d5fe Changed implementation of convergence test from 
||r|| < tol^2 * ||b||
to
    ||r|| / ||b|| < tol^2

in pcg.c smg_solve.c and pfmg_solve.c

This addresses the bug Marty Marinak saw when ||b||*tol^2
evaluates to zero.

05006d2259 - Added new StructCoarsen routine to improve setup phase scalability. 
- Added generic semicoarsening interpolation/restriction routines,
  and changed PFMG/SMG to use (no more IntAdd in SMG).
- Modified SMG solve code to always do one V-cycle.  PFMG/SMG solve
  routines now look nearly identical.
- SparseMSG is broken in this revision.

983b0bd9f8 Added code to set interpolation to zero if the corresponding stencil 
entry is zero. This fixes a bug Louis Howell saw in AMR where there
were non-zero interpolation weights, and thus non-zero coarse grid
operators, reaching outside the domain.

6a9fa7af16 Fixed problem with automatic generation of pthreads wrapper functions 
not handling pointer-to-function types correctly.  The fix should be
considered temporary, and it involves adding a typedef to the public
header file with a lower-case 'hypre_' prefix.

9bc956693b Modified PFMG to skip relaxation of certain levels - makes 
it behave more like a full coarsening method. This results
in a faster algorithm for isotropic problems. Currently
have set defaults to relax on all levels, so code runs as
before. To skip levels, use the SetSkipRelax routines
to set skip_relax flag to 1.
We should be able to save a bit of storage by freeing up
operators on levels where no relaxation will be done.
I tried the obvious thing, the code ran fine, but purify
complained. Thus, the code I check in makes no attempt to
free these operators.

ac15746679 Took InitializeShell routines out of NewRAP and NewInterpOp routines 
and put them into the PFMG_Setup and SMG_Setup code.  This makes the
NewRAP and NewInterpOp routines consistent (equivalent) in functionality
to the NewMatrix routine.
