--[[
Register a saved variable to be initialized to a default value
if it is nil once the addon's saved variables are loaded.
Can handle N-depth table values as well without requiring initialization of the tables themselves.
The addon saved variable defaults will be automatically initialized at the addon's ADDON_LOADED event,
or they can be forced to load using lib:InitAddOn(addonName).
 
Usage:
loader:SetDefault("MyAddOn", "SavedVar(Table)Name", [key1, [key2, [...] ] ], value)
Example Usage:
local loader = LibStub("LibDefaults")
loader:SetDefault("MyAddOn", "SavedVarName", SavedVarValue)

--[[
Register a function to be executed once an addon's variables have been loaded.
Fires after addon defaults have been set.
 
Usage:
SetDefault("MyAddOn", "SavedVar(Table)Name", [key1, [key2, [...] ] ], value)
Example Usage:
local loader = LibStub("LibDefaults")
loader:SetScript("MyAddOn", function(addonName) dostuff() end)
