/////////////////////////////////////////////////////////////////////////////
// map_def: map definitions for maps loaded from .des files.
//
// Please read this before changing map_def.
//
// When adding Lua-visible fields to map_def, note that there are two
// kinds of fields:
//
// * Fields that determine placement of the map, or are unchanging,
// such as "place", "depths" (determine placement), or "name" (does
// not change between different evaluations of the map). Such fields
// must be reset to their default values in map_def::init() if they
// determine placement, or just initialised in the constructor if
// they will not change.
//
// * Fields that do not determine placement and may change between
// different uses of the map (such as "mons", "items",
// "level_flags", etc.). Such fields must be reset to their default
// values in map_def::reinit(), which is called before the map is
// used.
//
// If you do not do this, maps will not work correctly, and will break
// in obscure, hard-to-find ways. The level-compiler will not (cannot)
// warn you.
