/** \class RelabelLabelMapFilter
* \brief This filter relabels the LabelObjects; the new labels are arranged
* consecutively with consideration for the background value.
*
* This filter takes the LabelObjects from the input and reassigns them to the
* output by calling the PushLabelObject method, which by default, attempts to
* reorganize the labels consecutively. The user can assign an arbitrary value
* to the background; the filter will assign the labels consecutively by
* skipping the background value.
*
