=item $html = TypeSelector($name,$class)

This subroutine generates the HTML for the type selector navigation
bar.  The links in the bar are dynamically generated based on the
values of $name and $class.  This function is called by PrintTop().
It is not exported by default.

=item $url = Url($display,$params)

Given a symbolic display name, such as "tree" and a set of parameters, 
this function looks up its URL and then calls ResolveUrl() to create a 
single Url.

When hard-coding relative URLs into AceBrowser scripts, it is
important to pass them through Url().  The reason for this is that
AceBrowser may need to attach the database name to the URL in order to
identify it.

Example:

  my $url = Url('../sequence_dump',"name=$name;long_dump=yes");
  print a({-href=>$url},'Dump this sequence');

=cut

sub Url {
  my ($display,$parameters) = @_;
  my $url = Configuration()->display($display,'url');
  return ResolveUrl($url,$parameters);
