## Tags :: dictionary[string → AnyBasic]

A dictionary of string to the four basic Lua types: `string`, `boolean`, `number`, `table`.

Note that the API returns tags as a simple table, meaning any modifications to it will not propagate back to the game. Thus, to modify a set of tags, the whole table needs to be written back to the respective property.

#### Example

    {a = 1, b = true, c = "three", d = {e = "f"}}
