 * A terminal node used in Object Allocation Profiling Calling Context Tree (CCT).
 * Contains the information gathered during object allocation profiling, which can be calculated  for intermediate nodes
 * if known for terminal nodes.
 * <p/>
 * Normally used as a leaf, except in case there are multiple same paths in the tree with differfent length
 * <p/>
 * The information in TermCCTNode represents all objects of the same type allocated using same call path.
