- An Administrator shall be able to configure the system by setting
- coordinates of the location where the system is operated lon/lat
- l/minute the sprinkler deploys when switched on
- earliest time in the morning the system may sprinkle
- latest time in the evening the system may sprinkle

- A user shall be able to arm/disarm the system
- A user shell be able to see the system operation log
- The system operation log shall show the amount of water that has been irrigated as an equivalent mm rain / day and the total liters for the area

Use cases
configure system
As an administrator I'd like to configure the system.
arm / disarm system
As a user I'd like to arm/disarm the system. When the system is armed it will automatically sprinkle. If the system is disarmed only manual operation of the sprinkler is possible.
