There is one instance of WebStyle per each AIDASite, so tehre are omany
sessions per one webstyle.

WebStyle>>session finds a current session on which this method is
called, by "climbing on the stack", that is, going up on the stack to
find a first reference to the session this call is executing. See
Object>>firstSessionFromStack method.

This also means that #session method must be called always while
processing a web request. If you call it from debugger or workspace, it
won't find a session of course and you'll end up in error.
