// Hyperbolic Rogue
// Copyright (C) 2011-2016 Zeno Rogue, see 'hyper.cpp' for details
// Hyperbolic geometry is a good tool to visualize data,
// especially trees and scale-free networks. This file
// uses HyperRogue to browse such vizualizations.
// Since it is not of use for general HyperRogue players,
// it is disabled by default -- compile with the ROGUEVIZ flag to enable this.
// How to use:
// hyper -embed <start of filename> -- visualize a social network
// embedded into hyperbolic plane, see:
// https://bitbucket.org/HaiZhung/hyperbolic-embedder/overview
// (it uses the same format)
// hyper -tess <parameter file> -- visualize a horocyclic tesselation,
