/**
 * <p>Simple factory to create {@link Reviser} objects.  Two methods to create scenes
 * exist.  One takes only a VComponent as a parameter and builds an empty {@link Reviser}.
 * The second takes a VComponent and an array of parameters required to completely
 * initialize the {@link Reviser}.</p>
 * 
 * <p>The parameters array contains the following:
 * <ul>
 * <li>{@code Callback<Map<ChangeDialogOption, Pair<Temporal, Temporal>>, ChangeDialogOption>} - callback for user dialog
 * <li>Temporal - endRecurrence, end of selected recurrence
 * <li>Temporal - startRecurrence, start of selected recurrence
 * <li>Temporal - startOriginalRecurrence, start of selected recurrence
 * <li>VComponent - VComponent with non-time changes applied
 * <li>VComponent - copy of original unchanged VComponent
 * </ul>
 * </p>
