/** \file bigstuff.cpp
* \brief Large map structures, such as (horo)cycles and equidistants.
*
* This file implements:
* * routines related to (horo)cycles
* * routines related to equidistants
* * 'setland' routines for other geometries
* * the buildBigStuff function which calls equidistant/(horo)cycle/barrier generators.
* This routines are general, i.e., not necessarily Steam-specific.
