Detailed Description

Base class for all cover devices.

Covers currently have three properties:

position - The current position of the cover from 0.0 (fully closed) to 1.0 (fully open). For covers with only binary OPEN/CLOSED position this will always be either 0.0 or 1.0
tilt - The tilt value of the cover from 0.0 (closed) to 1.0 (closed)
current_operation - The operation the cover is currently performing, this can be one of IDLE, OPENING and CLOSING.

For users: All cover operations must be performed over the .make_call() interface. To command a cover, 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 cover, use the public .position, .tilt 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 cover. Also implement get_traits() to return what operations the cover supports.
