=head2 over

  my $result = $self->over($iterable, sub {
      my ($item, $info) = @_;
      return "<p>Item: $item, Index: " . $info->current . "</p>";
  });

In a template:

  <%= over($iterable, sub($item, $info) {
      <p>Item: <%= $item %>, Index: <%= $info->current %></p>
  }) %>

(Remember in the template calling helpers via C<$self> is your option)

Executes a callback for each item in an iterable, providing metadata about the iteration 
through a L<Catalyst::View::EmbeddedPerl::PerRequest::EachInfo> object.

Although you can use standard Perl looping constructs in your templates, the C<over>
helper provides the addional metadata about the iteration that can be useful in some
situations related to display logic, such as changing the CSS based on even/odd rows
or tracking the item number.
