Contract purpose
This Smart Contract manages the monthly payments for the employees of a company. The system manager is in charge of adding all the employee's details( account address, job start date) to the contract list. The system manager is also in charge with updating the employee's job end date when an employee leaves the job. The constructor is payable, meaning that when the contract is created, some amount of ether has to be sent to the contract's balance. From this balance, the payments to the employees are made. The manager can increase this balance at any time.
