/**
 * A CreateFolderOperation represents an undoable operation for creating a
 * folder in the workspace. If a link location is specified, the folder is
 * considered to be linked to the specified location. If a link location is not
 * specified, the folder will be created in the location specified by the
 * handle, and the entire containment path of the folder will be created if it
 * does not exist.  The folder should not already exist, and the existence 
 * of the containment path should not be changed between the time this operation
 * is created and the time it is executed.
