=head1 NAME

Pisg::HTMLGenerator - class to create a static HTML page out of data parsed

=head1 DESCRIPTION

C<Pisg::HTMLGenerator> uses the hash returned by Pisg::Parser::Logfile and turns it into a static HTML page.

=head1 SYNOPSIS

    use Pisg::HTMLGenerator;

    $generator = new Pisg::HTMLGenerator(
        cfg => $cfg,
        stats => $stats,
        users => $users,
        tmps => $tmps
    );

=head1 CONSTRUCTOR

=over 4

=item new ( [ OPTIONS ] )

This is the constructor for a new Pisg::HTMLGenerator object. C<OPTIONS> are passed in a hash like fashion using key and value pairs.

Possible options are:

B<cfg> - hashref containing configuration variables, created by the Pisg module.

B<stats> - reference to the hash returned by Pisg::Parser::Logfile containing all stats.

B<users> - reference to a hash containg user information

B<tmps> - reference to a hash containing the language templates.
