/**
 * \class DListVal
 * \brief By-value doubly linked list.
 *
 * This class is a doubly linked list that does not require a list element
 * type to be declared. The user instead gives a type that is to be stored in
 * the list element. When inserting a new data item, the value is copied into
 * a newly allocated element. This list is inteded to behave and be utilized
 * like the list template found in the STL.
 *
 * DListVal is different from the other lists in that it allocates elements
 * itself. The raw element insert interface is still exposed for convenience,
 * however, the list assumes all elements in the list are allocated on the
 * heap and are to be managed by the list. The destructor WILL delete the
 * contents of the list. If the list is ever copied in from another list, the
 * existing contents are deleted first. This is in contrast to DList and
 * DListMel, which will never delete their contents to allow for statically
 * allocated elements.
