lower_bound_search(+Tree, ++SearchKey, ?Key, ?Value)

   Search a tree for the smallest key no smaller than SearchKey.

Arguments
   Tree                A 2-3-4 tree
   SearchKey           A key to search for
   Key                 The key found
   Value               The value corresponding to Key

Type
   library(m_tree234)

Description
	
	This predicate searches the tree Tree for the entry with the
	smallest key which is no smaller than SearchKey.  If such a key is
	found, then it attempts to unify it with Key and the corresponding
	value with Value.
	
	
	This predicate should only be called with trees created by other
	predicates from the tree234 module.
	
	

Fail Conditions
   Fails if there are no keys at least as large as SearchKey in Tree or if Key and Value do not unify with the key and value found.

Resatisfiable
   no
