Kaiketsu 0.5

Kaiketsu is a simple sudoku solver. You only have to insert a scheme and press the solve button.
Installation:
The simplest way to compile this package is:
1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute `configure itself.
Running `configure takes a while. While running, it prints some messages telling which features it is checking for.
2. Type `make to compile the package.
3. Type `make install to install the programs and any data files and documentation.
4. You can remove the program binaries and object files from the source code directory by typing `make clean
Enhancements:
- Cedric LeGloannec improved the speed and now it is possible to find all the solutions of a scheme and save them into a file.
