 * Imagine the continuity of a Clap file

 * This serves multiple purpose, such as being able to create
 * long stories in a more streamed way
 * 
 * This should integrate multiple factors such as the event history, actions etc
 *
 * Be careful however as the context will grow at the same time as the story
 * (it's the same issue as in the AI Comic Factory)
 * so it may become harder and/or slower to perform the query
