Step Identifier Tracker
class StepIdentifierTracker constructor(initialTable: MutableList<String> = mutableListOf()) : StepTracker
Provides a simple implementation of a StepTracker that uses StepIdentifier to track if a Step has been seen. Optionally the table can be provided. This provides a simple mechanism for tracking steps and may not be suitable for games with greater than 100,000 steps as the lookup will become more costly and serialization less suitable.
