ItemTypeMatcher

ItemTypeMatcher(short type)

type - the type to search for. This may be

• MapItem.TELEPORT
• MapItem.WELL
• MapItem.EXIT
• MapItem.CARD
• MapItem.SLEEPING_ROBOT
• MapItem.UNKNOWN_REACTABLE

Probably also works for MapItem.EMPTY, MapItem.WALL, MapItem.ROBOT and MapItem.UNKOWN_ITEM, however the sense of these seems quite limited.
