        * src/tools: New directory created for tools.

        * src/tools/solver: Moved src/solver-lp.c into here and split it
        into two files: src/tools/solver/solver.c and
        src/tools/solver/reports.c.  A _major_ rewrite.

        * src/tools/solver/lp_solve: Integrated key parts of an LGPLed
        linear programming toolkit called LP Solve 3.2.  (The whole
        package can be found from ftp://ftp.ics.ele.tue.nl/pub/lp_solve).
        Major clean up for making it to look like GNOME code.  LP Solve is
        written by Michel Berkelaar and others.  Thanks for the great
        work!

        * configure.in: Added src/tools/Makefile, src/tools/solver/Makefile,
        and src/tools/solver/lp_solve/Makefile.

        * src/Makefile.am: Added tools subdirectory.

        * src/mathfunc.[ch]: Removed all solver related functions.

        * src/solver.h, src/sheet.c: solver_lp_new renamed as
        solver_param_new.  solver_lp_destroy renamed as
        solver_param_destroy.

        * src/xml-io.c: Solver related changes.

        * samples/solver/production-plan.gnumeric: A Solver sample file.
