Detailed Description

template<typename GraphType>
class limbo::algorithms::coloring::MISColoring< GraphType >

MIS based graph coloring, which means iteratively search for the maximum independent set.
Edge weight is used to differentiate conflict edge and stitch edge. Non-negative weight implies conflict edge, while negative weight implies stitch edge.
