Editing WoW:Creating GUI configuration options (section)

==== Globals ====

We need to:
* Get the Realm and Character names for later
* Ensure SavedVariable 'myClockConfig' exists
* Create addon details for myAddOns
* Create default config settings

'''myClockIndicatorFrame.lua'''
  ...
  -- Globals
    -- so we know when our configuration is loaded
  myClock_variablesLoaded = false;
    -- for configuration saving
  myClockRealm = GetCVar("realmName");
  myClockChar = UnitName("player");
    -- details used by myAddOns
  myClock_details = {
 	name = "myClock",
 	frame = "myClockIndicatorFrame",
 	optionsframe = "myClockConfigFrame"
  };
    -- default config settings
  local myClockConfig_defaultOn = true;		-- addon enabled?
  local myClockConfig_defaultTime24 = true; 	-- 24 hour format?
  local myClockConfig_defaultOffset = 0; 	-- time offset?
  ...

;myClock_variablesLoaded, myClock_realm, myClock_char : These are needed to create a table of settings, per-realm, per-character.  By default a SavedVariable is only per-account.  This way changing configuration options on one character does not change them for all your characters!
;myClock_details : [[myAddOns]] will display information about your AddOn, and needs the name of your main and config frames to display the configuration dialog properly.
; myClockConfig_default : Each of these variables is a default setting for a configuration option the user will be able to change in our config dialog.  They are also used the first time a character uses our addon, as they have no saved settings yet.
