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.

TitanBarData ^^: Titan static bar reference and placement info
TitanAll is used for settings used for Titan itself such as use global profile, tootip modifier, etc.
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 : 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).


TitanSettings has major sections with associated shortcuts in the code
TitanPlayerSettings =		TitanSettings.Players[toon]
TitanPluginSettings =		TitanSettings.Players[toon].Plugins		: Successful registered plugins with all flags
TitanPanelSettings =		TitanSettings.Players[toon].Panel		: **
TitanPanelRegister =		TitanSettings.Players[toon].Register	: .registry of all plugins (Titan and LDB) to be registered with Titan
TitanBarDataVars ^^=		TitanSettings.Players[toon].BarVars		: Titan user selected placement info
TitanAdjustSettings =			TitanSettings.Players[toon].Adjust		: List of frames Titan can adjust, vertically only

** :
- Has Plugin placement data under Location and Buttons
- Bar settings Show / Hide, transparency, skins, etc
- Per character Titan settings plugin spacing, global skin, etc

^^ :
- The index is the string name of the Titan Bar to coordinate staic and user selected bar data

-- 3 button frames are used to create a Titan bar:
-- the 'display' button frame - the bar itself,

DESC:
The table holds:
- the name of each Titan bar (as the index)
- the short name of the bar
- whether the bar is relative - top or bottom or short (user placed)
- the order they should be considered
- SetPoint values for show / hide
- short bar specific values

The short name is used to build names of the various saved variables, frames,
 and buttons used by Titan.
