Package Exports
- history-tree
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (history-tree) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Synchronous. Creates a new history sub-tree and adds it to the checkpoint stack.
historyTree.commit(cb)
Asynchronous.
Removes the top sub-tree from the checkpoint stack,
calls commitAll on the sub-tree,
then emits commit on this tree.
If it was the last checkpoint on the stack, this tree emits resolve.
Calls the callback with an Error if the stack is empty.
historyTree.revert(cb)
Asynchronous.
Removes the top sub-tree from the checkpoint stack,
calls revertAll on the sub-tree,
then emits revert on this tree.
If it was the last checkpoint on the stack, this tree emits resolve.
Calls the callback with an Error if the stack is empty.
historyTree.commitAll(cb)
Asynchronous.
Calls commit on this tree for all checkpoints on the stack, in series.
Does NOT call the callback with an Error if the stack is empty.
