Print a hierarchical random graph model to the screen

igraphHRG objects can be printed to the screen in two forms: as a tree or as a list, depending on the type argument of the print function. By default the auto type is used, which selects tree for small graphs and simple (=list) for bigger ones. The tree format looks like this: Hierarchical random graph, at level 3: g1 p= 0 '- g15 p=0.33 1 '- g13 p=0.88 6 3 9 4 2 10 7 5 8 '- g8 p= 0.5 '- g16 p= 0.2 20 14 17 19 11 15 16 13 '- g5 p= 0 12 18 This is a graph with 20 vertices, and the top three levels of the fitted hierarchical random graph are printed. The root node of the HRG is always vertex group #1 (g1 in the the printout). Vertex pairs in the left subtree of g1 connect to vertices in the right subtree with probability zero, according to the fitted model. g1 has two subgroups, g15 and g8. g15 has a subgroup of a single vertex (vertex 1), and another larger subgroup that contains vertices 6, 3, etc. on lower levels, etc. The plain printing is simpler and faster to produce, but less visual: Hierarchical random graph: g1 p=0.0 -> g12 g10 g2 p=1.0 -> 7 10 g3 p=1.0 -> g18 14 g4 p=1.0 -> g17 15 g5 p=0.4 -> g15 17 g6 p=0.0 -> 1 4 g7 p=1.0 -> 11 16 g8 p=0.1 -> g9 3 g9 p=0.3 -> g11 g16 g10 p=0.2 -> g4 g5 g11 p=1.0 -> g6 5 g12 p=0.8 -> g8 8 g13 p=0.0 -> g14 9 g14 p=1.0 -> 2 6 g15 p=0.2 -> g19 18 g16 p=1.0 -> g13 g2 g17 p=0.5 -> g7 13 g18 p=1.0 -> 12 19 g19 p=0.7 -> g3 20 It lists the two subgroups of each internal node, in as many columns as the screen width allows.
