A runnable which executes as a batch operation within the workspace.
The IWorkspaceRunnable interface should be implemented
by any class whose instances are intended to be run by
IWorkspace.run.
Runs the operation reporting progress to and accepting
cancellation requests from the given progress monitor.
Implementors of this method should check the progress monitor
for cancellation when it is safe and appropriate to do so. The cancellation
request should be propagated to the caller by throwing
OperationCanceledException.
Parameters:
monitor - a progress monitor, or null if progress
reporting and cancellation are not desired
