/**
* A helper class that contains the state of the audit progress performed by
* the accessibility panel. Its onProgressForWalker function wraps around the
* onProgress function (see actions/audit.js) that updates the panel state. It
* combines the audits across multiple frames that happen asynchronously. It
* only starts dispatching/calling onProgress after we get an initial progress
* audit-event from all frames (and thus know the combined total).
