=head1 NAME
FML::CGI::ThreadTrack - CGI details to control thread system
=head1 SYNOPSIS
$obj = new FML::CGI::ThreadTrack;
$obj->prepare();
$obj->verify_request();
$obj->run();
$obj->finish();
run() executes html_start(), run_cgi() and html_end() described below.
See L<FML::Process::Flow> for flow details.
=head1 DESCRIPTION
=head2 CLASS HIERARCHY
C<FML::CGI::ThreadTrack> is a subclass of C<FML::Process::CGI>.
=head1 METHODS
Almost methods common for CGI or HTML are forwarded to
C<FML::Process::CGI> base class.
