+ * This class is used when Location Framework needs to acquire a position and 
+ * quality from the PSY. The interface of this class is used for loading and 
+ * using PSYs and as a framework for developing PSYs. It requires that users 
+ * define new subclasses to the API classes. It is also used for implementing
+ * more advanced PSY features, e.g. periodic position updates, and the maximum 
+ * age for positions. It can also handle parallel requests.
