NAME: TitanVariables.lua
DESC: This file contains the routines to initialize, get, and set the basic data structures used by Titan. 
It also sets the global variables and constants used by Titan.

TitanSettings, TitanSkins, ServerTimeOffsets, ServerHourFormat are the structures saved to disk (listed in toc).
TitanSettings: is the table that holds the Titan variables by character and the plugins used by that character.
TitanSkins: is the table that holds the list of Titan and custom skins available to the user. It is assumed that the skins are in the proper folder on the hard drive. Blizzard does not allow addons to access the disk.
ServerTimeOffsets and ServerHourFormat: are the tables that hold the user selected hour offset and display format per realm (server).
