Includes all tuple headers.

A tuple is a fixed size collection of elements.

In the preprocessor library, tuples are represented like macro parameter lists. Thus an element of a tuple can be any sequence of tokens that constitutes a single macro parameter.

Examples of tuples:

      (const, volatile)    // 2-tuple
      (*, /, %)            // 3-tuple
      (1, "2", '3', (4,5)) // 4-tuple

Tuples can be used for representing structured data.
