Notes:
	* Sets a saved variable so as to correlate to the database table.
	* Setting the charName is unnecessary if you never use char-specific data. If you do use them, it can be a good idea to have.
	* This is to be called before ADDON_LOADED
Arguments:
	string - global name of the saved variable.
	string - global name of the per-character saved variable.
Example:
	MyAddon:SetDatabase("MyAddonDB")
	-- or
	MyAddon:SetDatabase("MyAddonDB", "MyAddonCharDB")
-----------------------------------------------------------------------------]]

--[[---------------------------------------------------------------------------
Notes:
	* Acquires a namespace within the database.
	* This is especially handy for a module system to use, simply get a namespace with the same name as your module, and it acts as a fully functioning database.
Arguments:
	string - name of the namespace
Example:
	MyAddon_Bank.db = MyAddon:AcquireDBNamespace("Bank")

Notes:
	* Set default values for a specific database type.
	* The defaults table can have subtables as well (as many as you want). This can be used to define your basic db structure.
	* You can also set a whole table's default value by using the special key ['*'], which even works with tables.
	* There is another key, ['**'], which does the same thing as ['*'] ''but'' also populates inside sibling nodes. For example, <tt>{ ['**'] = { alpha = true, bravo = true, charlie = true}, monkey = { bravo = false } }</tt> makes monkey behave like <tt>{ alpha = true, bravo = false, charlie = true }</tt>
	* If you use the 'profile' dataType, it applies to ''all'' profiles.
	* This is to be called between `SetDatabase' and ADDON_LOADED.
Arguments:
	string - "char", "class", "realm", "server", "account", "faction", or "profile" - correlates to the type of data you're working with.
	table - the defaults
Example:
	MyAddon:SetDatabaseDefaults('char', {
	    alpha = {
	        bravo = {
	            charlie = true
	        }

	* You can also set a whole table's default value by using the special key ['*'], which even works with tables.
	* There is another key, ['**'], which does the same thing as ['*'] ''but'' also populates inside sibling nodes. For example, <tt>{ ['**'] = { alpha = true, bravo = true, charlie = true}, monkey = { bravo = false } }</tt> makes monkey behave like <tt>{ alpha = true, bravo = false, charlie = true }</tt>
	* If you use the 'profile' dataType, it applies to ''all'' profiles.
	* This is to be called between :SetDatabase and ADDON_LOADED.
Arguments:
	string - name of the namespace
	string - "char", "class", "realm", "server", "account", "faction", or "profile" - correlates to the type of data you're working with.
	table - the defaults
Example:
	MyAddon:SetDatabaseNamespaceDefaults('Bank', 'char', {
	    value = 50
	})

Notes:
	* If you are in a char, class, or realm profile, "short" will be "char", "class", or "realm" and "long" will be "char/Player of Realm Name", "class/Warlock", or "realm/My Realm - Horde". Otherwise, "short" and "long" will be equivalent.
	* "Default" is the default profile unless specified by :SetDefaultProfile.
	* This is only accurate after ADDON_LOADED.
Returns:
	; "short" : string - The current profile, short-form.
