/** \class AttributeSelectionLabelMapFilter
* \brief remove the objects according to the value of their attribute
*
* AttributeSelectionLabelMapFilter removes the objects in a label collection image
* with an attribute value inside or outside a set of attribute values passed by
* the user.
* The attribute is provided by an attribute accessor given in template parameter.
* Contrary to the other filters made to remove some object of a LabelMap, no
* ordering relation for the attribute is needed in that filter.
* The filter provides two outputs: the first contains the surviving objects,
* the second the removed objects (the input LabelMap is the union of these two LabelMaps).
