<pre style='white-space:pre-wrap;width:81ex'>Entity relations: Initial multilevel API implementation

Relations API controls various interactions between entities, such as friendliness or hostility.

Relations API is split into three tiers:

* Tier 1: direct reverse engineered gameplay logic from the game
* Tier 2: server-side extension to plug holes left by original client-side perspective
* Tier 3: custom server-side convinience API for CMaNGOS

For more information, please refer to Relations.cpp inlined documentation.

Brief contents index for this patch is listed below.
