=item Class: B<OnWindowLoad>

Manages and call functions after the window.onload event in sequence

=over 4

=item SYNOPSIS

  new OnWindowLoad( function() {
    // do some stuff
  } );

  new OnWindowLoad( function() {
    // do some stuff
  }, { load_last: true } );


=item DESCRIPTION

Different browsers execute events attached to window.onload in different order.  For example, IE executes them in the reverse order compared to Firefox.  This class manages lists of functions and calls them squentially in the order that they were added.

Optionally you can specify a flag to have the function executed last (or nearly last).
