[Insight-users] Rescale label image

[Bill Lorensen]

/**
 * \class RelabelComponentImageFilter
 * \brief Relabel the components in an image such that consecutive
labels are used.
 *
 * RelabelComponentImageFilter remaps the labels associated with the
 * objects in an image (as from the output of
 * ConnectedComponentImageFilter) such that the label numbers are
 * consecutive with no gaps between the label numbers used.  By
 * default, the relabeling will also sort the labels based on the size
 * of the object: the largest object will have label #1, the second
 * largest will have label #2, etc.
 *
 * Label #0 is assumed to be background is left unaltered by the
 * relabeling.
