* A class for storing application state to do with the session. This is a simple flux
|
|
* store that listens for actions and updates its state accordingly, informing any

* listeners (views) of state changes.
|
|
*
|
|
* Usage:
|
|
* ```
|
|
* sessionStore.addListener(() => {
|
|
* this.setState({ cachedPassword: sessionStore.getCachedPassword() })
|
|
* })
|
