Added:
- Authentication_Control stateful bean to handle authentication access.
- SavingsAcc_control stateless bean to handle all savings-related actions.
- Stateless_SessionBeans is basically used to test addCustomer() and addEmployee()
- 1 table named EMP_CANDY(why this name? fancy so it's not a target) is created to store employee's password.
- EMP_CANDY contains password stored as Base64 hashcode.

Modified:
- float to double in all related files(e.g. Savings, Transactions, etc)
- RDBCustomerDAO, RDBEmployeeDAO, RDBSavingsDAO, RDBTransactionsDAO to handle actions properly
- Main.java includes all the functions for primary uses cases

Handling Timeout:
I have created a function check() to check if the session has timed out.
For every action, check() is invoked.

Known Issues:
- Exception for server's side is not handled properly.
- Logout is not done yet.
- There is no way to quit from user input.
