This class is a type of callback, and when triggered will
resolve all error log entries that have the specified callout.
It does this by setting the Resolved property on the log entry.
It can be used to do things like resolve all errors against a
particular part when that part is replaced, which would be done
by specifying this class as a callback on a watch on the Present
property for the part in the inventory.
