# progressTracker

`val progressTracker: ProgressTracker`
Overrides Primary.progressTracker

Override this to provide a ProgressTracker. If one is provided and stepped, the framework will do something helpful with the progress reports. If this protocol is invoked as a sub-protocol of another, then the tracker will be made a child of the current step in the parent. If its null, this protocol doesnt track progress.

Note that this has to return a tracker before the protocol is invoked. You cant change your mind half way through.
