Add a table of contents page on every documentation.

Feature request

I am suggesting a table of contents on each documentation.

Summary

The table of contents should start with entry into the language or framework, then functional or class reference of it.

This will make sure that everyone getting started on a language has a clear flow of knowledge from easy to expert, then for the experts, functional reference list will be a plus

Examples

lets say we want to create a table of contents for html:

Table of Contents: HTML
What is html ........................................................ 1
Evolution of HTML ............................................ 2
some feature ....................................................... n

Functional References
function one ......................................................... n +2
