/**
* Cursors
* -------
*
* Cursors allow you to hold a reference to a path in a nested immutable data
* structure, allowing you to pass smaller sections of a larger nested
* collection to portions of your application while maintaining a central point
* aware of changes to the entire data structure.
*
* This is particularly useful when used in conjuction with component-based UI
* libraries like [React](http://facebook.github.io/react/) or to simulate
* "state" throughout an application while maintaining a single flow of logic.
*
* Cursors provide a simple API for getting the value at that path
* (the equivalent of `this.getIn(keyPath)`), updating the value at that path
* (the equivalent of `this.updateIn(keyPath)`), and getting a sub-cursor
* starting from that path.
*
* When updated, a new root collection is created and provided to the `onChange`
* function provided to the first call to `Cursor(map, onChange)`.
*
* When this cursor's (or any of its sub-cursors') `update` method is called,
* the resulting new data structure will be provided to the `onChange`
* function. Use this callback to keep track of the most current value or
* update the rest of your application.
