Suggestion on the web service call and structure.

For calling the web service, we need a thread to handle instead of writing to activity class.

Currently using Customized Thread + Handler + Message (Serializable) to handle.

In the CampuspyServiceClient class, init each method to call each service API and then give the handle to dispatch the result to different callbacks in the corresponding activity.

Need to verify whether there's a better way to handle the whole process.
