History links: Keep track and link to pages browsed by user

This class can be used to keep track of the pages navigated by an user, so it can generate back or next links providing a similar effect to the use of the Javascript history.go() function.

It uses sessions to store an array variable that holds the URL of each page of a site that the user accesses.

It can limit the number of pages that are kept in the history array.

It may also ignore pages accessed with the POST method or with certain URLs based on options that define exclusion regular expressions.

The class can generate links to go back to the last page or even to the first page that was recorded.
