Command line tool for executing various algorithms

[Alpar Juttner]

This tool would read a .lgf file and run an algorithm on it. Finally it would report about the result or write the solution into a file. It should provide a wide range of algorithms which could be selected with command line options.

This is somewhat similar to that are proposed in #226, but I think they should be separate tools, as that one have a quite limited feature set, while this one will probably become a complex tool with tons of option with the time.
