// An example for using BipartiteGraphBicoloringInterface to color Bipartite Graph
/*
How to compile this driver manually:
	Please make sure that "baseDir" point to the directory (folder) containing the input matrix file, and
		s_InputFile should point to the input file that you want to use
	To compile the code, replace the Main.cpp file in Main directory with this file
		and run "make" in ColPack installation directory. Make will generate "ColPack.exe" executable
	Run "ColPack.exe"

Note: If you got "symbol lookup error ... undefined symbol "
  Please make sure that your LD_LIBRARY_PATH contains libColPack.so

Any time you have trouble understanding what a routine does, how to use a routine, or what are the accepted values for a parameter,
please reference the COLPACK's online documentation (temporarily located at
http://www.cscapes.org/dox/ColPack/html/ ).
