Graph specification for graph coloring
The edges are described by an array of integers with even number of elements, terminated by the elements -1,-1. The cliques are described by an array of integers, where the first integer gives the size of the clique, the following elements are nodes for each clique. The cliques are terminated by -1 for clique size
const int	g1_e []
	First example graph: edges.
const int	g1_c []
	First example graph: cliques.
const GraphColorSpec	g1 (200, g1_e, g1_c)
	First example graph.
const int	g2_e []
	Second example graph: edges.
const int	g2_c []
	Second example graph: cliques.
const GraphColorSpec	g2 (200, g2_e, g2_c)
	Second example graph.
