-// An ApplicationState object stores information about Chrome's status in the
-// iOS application lifecycle and owns root-level global objects needed
-// throughout the app (specifically, |browserState| and |window|).
-// Additionally, an ApplicationState object keeps arrays of steps to perform
-// in response to various changes in the overall application states.
-// These steps are grouped into launch (used when the app is cold starting),
-// termination (used when the app is shutting down), background (used when the
-// app is backgrounding but staying resident), and foreground (used when the app
-// is warm starting). Each group of steps is an ordered array of objects
-// implementing the ApplicationStep protocol.
-// Some methods (indicated below) will cause the ApplicationState to run one of
-// these lists of steps; this consists of:
-// (1) Calling -canRunInState: on the first item in the list, passing in the
-// running ApplicationState object. If this returns NO, stop. Otherwise:
-// (2) Removing the first item from the list and then calling -runInState:,
-// again passing in the current state object. State objects can assume
-// that they are no longer in the step array once -runInState: is called.
-// (3) When runInState: completes, going back to (1). Since the list of steps
-// had ownership of the application step that just ran, that step will
-// then no longer be strongly held, and will thus be deallocated unless
-// it is being strongly held elsewhere.
-// Steps cannot themselves store state, since they don't persist after running
-// by default. Steps can write to the ApplicationState's |state| object to
-// store state.
