+* These are a number of methods that work into the calling function.
+*
+* @param guid Requires a guid to call
+* @return Name, Gender, Race, Class and Level of player character
+* Example Usage:
+* @code
+*    CharacterCacheEntry const* characterInfo = sCharacterCache->GetCharacterCacheByGuid(GUID);
+*    if (!characterInfo)
+*        return;
+*

+*    uint8 playerRace = characterInfo->Race;
+*    uint8 playerClass = characterInfo->Class;
+*    uint8 playerLevel = characterInfo->Level;
