1. This procedure calls insightupdate for each progress metric supported.

2. By default, mminsight registers the insightupdateprogress function provided by the mminsight package as the callback function for the gapnotify callback. The insightupdateprogress function calls insightupdate for any metric that has changed. It is expected that the developer will only need to call insightupdate directly if the gapnotify callback is registered against a function provided by the developer.
