/** Base class for all valve devices.
*
* Valves currently have three properties:
* - position - The current position of the valve from 0.0 (fully closed) to 1.0 (fully open).
* For valves with only binary OPEN/CLOSED position this will always be either 0.0 or 1.0
* - current_operation - The operation the valve is currently performing, this can
* be one of IDLE, OPENING and CLOSING.
*
* For users: All valve operations must be performed over the .make_call() interface.
* To command a valve, use .make_call() to create a call object, set all properties
* you wish to set, and activate the command with .perform().
* For reading out the current values of the valve, use the public .position, etc.
* properties (these are read-only for users)
*
* For integrations: Integrations must implement two methods: control() and get_traits().
* Control will be called with the arguments supplied by the user and should be used
* to control all values of the valve. Also implement get_traits() to return what operations
* the valve supports.
