Update ChannelManager (#41)
* Update Channel Manager Switch ChannelManager to an interface. Extend with an ArrayChannelManager (and copy the code). Update the config to allow for swapping. Bind it to the ServiceProvider * Add a fallback if the config variable isn’t set * Fix StyleCI * Fix StyleCI line break * Add description for the ChannelManager option
