public class Login
extends Activity

The Login Activity is responsible for displaying the login screen for the administrative user to enter in probationer data into the application. Data collected here includes Site ID, Client ID, Session Number, RA ID, and Date. The application then verifies that both client ids match. Once all the fields have been entered and the administrative user presses the next button, this activity then loads a new activity corresponding to the session number entered in the Session Number field.
