示例1: GetAreas
/**
* Load areas which has a one for the types given by types. If at leats one node
* in one of the outer rings of the areas is marked in nodeUseMap as "used at least twice",
* index it into the areas map.
*
* If the number of indexed areas is bigger than parameter.GetRawWayBlockSize() types are
* dropped form areas until the number is again below the lmit.
