=head1 ui-lib.pl
Common functions for generating HTML for Webmin user interface elements.
Some example code :
use WebminCore;
init_config();
ui_print_header(undef, 'My Module', '');
print ui_form_start('save.cgi');
print ui_table_start('My form', undef, 2);
print ui_table_row('Enter your name',
ui_textbox('name', undef, 40));
print ui_table_end();
print ui_form_end([ [ undef, 'Save' ] ]);
ui_print_footer('/', 'Webmin index');

=head2 ui_table_start(heading, [tabletags], [cols], [&default-tds], [right-heading])
Returns HTML for the start of a form block into which labelled inputs can
be placed. By default this is implemented as a table with another table inside
it, but themes may override this with their own layout.
The parameters are :
=item heading - Text to show at the top of the form.
=item tabletags - HTML attributes to put in the outer <table>, typically something like width=100%.
=item cols - Desired number of columns for labels and fields. Defaults to 4, but can be 2 for forms with lots of wide inputs.
=item default-tds - An optional array reference of HTML attributes for the <td> tags in each row of the table.
=item right-heading - HTML to appear in the heading, aligned to the right.
