A class that encapsulates a host settings data store. 

A host settings data store contains settings that describe the server hosts that the LBS subsystem
uses. For example, for the SUPL protocol, the data store contains settings for the SUPL servers that are used
for location requests (from local client applications and from the network), settings that define the authentication
type that should be used between client and server and the internet access point to use for network connections.
This class has methods to create a new host settings store, to create, modify and delete host settings and set the host
settings that should be used as defaults.
