Description

Implements a map for unique IDs to arbitrary data. The ID-to-Data mapping is stored in an Average Level Binary Tree for fast indexing. The map also maintains a linked list between the ordered items for fast iteration through its elements. The ID can be signed or unsigned, with a size of 1, 2, 4, 8, 16 or 32 bytes. The data can be of any (constant) size.

TMap extends the ancestor class to include public methods which Add map items, and read or write their arbitrary data values.
