Detailed Description

template<typename T>
class list_head< T >

Simple list structure for items of type T, for use when being part
of a list is an inherent property of T.  T must have members equivalent
to "T *prev, *next;" and a function "void set_parent (list_head <T> *)"
to set the parent list.

release()

template<typename T >

list_head< T >::range list_head< T >::release

(

)

Replace OLDR with NEWR.  OLDR remains valid and can be inserted into
other lists.
