  90     Within a given area in a given game, encounters are differentiated by the
  91     "slot" they are in and the state of the game world.
  92
  93     What the player is doing to get an encounter, such as surfing or walking
  94     through tall grass, is called terrain.  Each terrain has its own set of
  95     encounter slots.
  96
  97     Within a terrain, slots are defined primarily by rarity.  Each slot can
  98     also be affected by world conditions; for example, the 20% slot for walking
  99     in tall grass is affected by whether a swarm is in effect in that area.
 100     "Is there a swarm?" is a condition; "there is a swarm" and "there is not a
 101     swarm" are the possible values of this condition.
 102
 103     A slot (20% walking in grass) and any appropriate world conditions (no
 104     swarm) are thus enough to define a specific encounter.
 105
