## Detailed Description

CSScreenSharingListener is a class that is responsible for two things:

1. It's a listener to a CSContentSharingDelegate which delegates events coming from collaboration server concerning content sharing.
2. It's a drawing delegate of CALayer behind a CSScreenSharingView object and it's responsible for drawing incoming frames on the layer.

Proper use of this class:

- Client creates a view of CSIOSScreenSharingView class
- Client creates a CSScreenSharingListener object (inited with sharing view's size)
- set contentSharingDelegate of CSIOSScreenSharingView to object of CSScreenSharingListener class

Client doesn't need to invoke methods of this class in order to make content sharing work unless custom screen sharing view is developed.
