Format for files:
Each block of text (with atleast 2 newlines) represents a StoryNode. StoryNodes follow this format:
{story id}: {story message}
> {action id}: {action message} | {next story}
> {action id}: {action message} | {next story}
Alternatively, if the story node should automatically move to the next node:
{story id}: {story message}
>> {action id}: {next story}
