=head1 NAME
JQuery::Heartbeat - an interface to JHeartbeat
=head1 VERSION
Version 1.00

=head1 SYNOPSIS
JHeartbeat installs the heartbeat javascript and calls the specified url on each timeout
    use JQuery;
    use JQuery::Heartbeat;
    $jquery = new JQuery(...) ; 
    JQuery::Heartbeat->new(addToJQuery => $jquery, remoteProgram => 'jquery_heartbeat_results.pl', rm => 'heartbeatRunMode', delay => 1000) ; 
     
    To force the various browsers into non-cache mode, a variable, counter, is automatically added to the end of the url.
