The name of the class containing the algorithm's implementation will continue to reference the "kopf2011" name
CMake is being used for the library, but I'll convert to autotools during Inkscape integration.
You can find an initial repo skel that copies the pixel data in a graph data structure and build instructions. I'm using Inkscape code convetions and Inkscape dependencies. I hope I didn't miss anything.
