/**
* Simple mechanism to defer event related callbacks
*
* Probably think twice whether your event should use this instead of
* editor's built-in `editor-plugin-analytics`
*
* Editor-Plugin-Analytics provides methods methods to dispatch events, and attach events into prosemiror transactions
* However we do not have access to the smart card context in prosemirror
*
* We are using this queue to relay events occurring in prosemirror (which does not have access to the react context)
* to be subscribed to elsewhere where the react context is available (contentComponent or otherwise) (smart card context)
* in order to be able to annotate events with additional attributes to events
