/**
 * The `History` class keeps track and manages a stack of routes that the user
 * has navigated to in their session.
 *
 * An item can be pushed to the top of the stack using the `push` method. An
 * item in the stack has a name and a URL. The name need not be unique; if it is
 * the same as the item before it, that will be overwritten with the new URL. In
 * this way, if a user visits a discussion, and then visits another discussion,
 * popping the history stack will still take them back to the discussion list
 * rather than the previous discussion.
