Split the story macro out into two macros
Now the story macro manages the story element sequence, while the navigator macro listens for the navigation events, and modifies the story tiddler as required. Also introduces a history tiddler that retains the history stack so that we can animate navigation properly (as distinct from animating the addition and removal of story elements). Note that the zoomin storyview isn't quite finished, but this is a stable point to commit these changes.

Displays a sequence of tiddlers defined in two JSON structures. The story tiddler is the sequence of tiddlers currently present in the DOM:
|
||||
|
||||
{
|
||||
tiddlers: [
|
||||
{title: <string>, template: <string>}
|
||||
]
|
||||
{title: <string>, draft: <string>}
|
||||
]
|
||||
}
|
||||
|
||||
The storyview is a plugin that extends the story macro to implement different navigation experiences.
|
||||
The optional `draft` member indicates that the tiddler is in edit mode, and the value is the title of the tiddler being used as the draft.
|
||||
|
||||
When the story tiddler changes, the story macro adjusts the DOM to match. An optional storyview plugin can be used to visualise the changes.
|
||||
|
||||
And the history tiddler is the stack of tiddlers that were navigated to in turn:
|
||||
|
||||
{
|
||||
stack: [
|
||||
{title: <string>}
|
||||
]
|
||||
}
|
||||
|
||||
The history stack is updated during navigation, and again the storyview plugin is given an opportunity to animate the navigation.
