	If your creep needs to find...
	(can be accessed as creep.pos, or any other RoomPosition)
	creep.pos.findClosestByRange(type, options) -- returns one object, type is FIND_xx, for example: target = creep.pos.findClosestByRange(FIND_MY_SPAWNS);
	creep.pos.findClosestByPath(type, options) -- as above, but more CPU costly (searches by real path, not distance)
	creep.pos.findInRange(type, range, options) -- array, type is FIND_xx. Searches in square. All 8 adjacent tiles to creep are in range 1
	creep.pos.lookFor(type) -- array of objects that are at same position as creep. Type is LOOK_xx, for example LOOK_CONSTRUCTION_SITES

	(can be accessed as creep.room, or any other Room)
	creep.room.find(type, options) -- array, type is FIND_xx, for example FIND_DROPPED_RESOURCES. Options can have filter - as a function or object, like
