tercio@0 1 --- AceConfigRegistry-3.0 handles central registration of options tables in use by addons and modules.\\
tercio@0 2 -- Options tables can be registered as raw tables, OR as function refs that return a table.\\
tercio@0 3 -- Such functions receive three arguments: "uiType", "uiName", "appName". \\
tercio@0 4 -- * Valid **uiTypes**: "cmd", "dropdown", "dialog". This is verified by the library at call time. \\
tercio@0 5 -- * The **uiName** field is expected to contain the full name of the calling addon, including version, e.g. "FooBar-1.0". This is verified by the library at call time.\\
tercio@0 6 -- * The **appName** field is the options table name as given at registration time \\
tercio@0 7 --
tercio@0 8 -- :IterateOptionsTables() (and :GetOptionsTable() if only given one argument) return a function reference that the requesting config handling addon must call with valid "uiType", "uiName".
