Updates

Db Interface:
- Updated that getLocations(int uid,char type) and getAllLocations(uid) will be returning LocationList object now
Output: LocationList
- Not sure how to handle updates?
- is there a way to do an exception handling?
- can we have getters and setters for location objects?
- how to access getType for subloc?



- Written methods:
+LocationList getLocations(uid,type)
+LocationList getAllLocations(uid)
+Location getLocation(lid,uid)
+- addLocation
+- addEvent
+- getEvent
