/** |
|
* This class is used to hold default values for an implementation of ISequenceState. |
|
* It could be removed in a phase 2, but it is currently used to limit the scope of |
|
* this refactoring: it allows client code to access sequence info without having to |
|
* worry about `currentSequence` being null. |
|
* In the future this should be removed and we should pass around the correct data |
|
* structure (i.e. SequenceState OR WindowState) based on the situation. |
