-// Loads a graph from a text file, generates constraints for each edge requiring them
-// to point downwards, and proceeds to produce a layout using libcola.
-// The input file format is 2 numeric node labels per line separated by a space,
-// each pair representing a directed edge.  Node labels are simply used as array
-// offsets so they should start from 0.
-// The graph should be connected.
-// Default input file is the matrix market 1138_bus graph.
-// Running times:
-//    no constraints - steepest descent solver: 149 seconds
-//    no constraints - conjugate gradient solver: 21.7 seconds
-//    dir-edge constraints - conj grad. solver: 155.69 seconds
