Session Token

This module allows you to retrieve data from the $_SESSION storage and use that
information inside any form which accepts tokens.

A good example can be the usage of a form which you want to populate with
data which has already been entered by the current (anonymous) user.

Another example is to populate a multistep form.

Developers can easily store and retrieve information from this storage using the
functions session_token_get($key) and session_token_set($key, $value).
