/**
* Generates a form containing a sole button that submits to the
* URL given by _$options_. Use this method instead of +link_to+
* for actions that do not have the safe HTTP GET semantics
* implied by using a hypertext link.
*
* The parameters are the same as for +link_to+. Any _html_options_
* that you pass will be applied to the inner +input+ element.
* In particular, pass
*
* 'disabled' => true/false
*
* as part of _html_options_ to control whether the button is
* disabled. The generated form element is given the class
* 'button-to', to which you can attach CSS styles for display
* purposes.
*
* Example 1:
*
* // inside of controller for "feeds"
* $url_helper->button_to('Edit', array('action' => 'edit', 'id' => 3));
*
* Generates the following HTML (sans formatting):
*
* <form method="post" action="/feeds/edit/3" class="button-to">
* <div><input type="submit" value="Edit" /></div>
* </form>
*
* Example 2:
*
* $url_helper->button_to('Destroy', array('action' => 'destroy', 'id' => 3 , 'confirm' => 'Are you sure?'));
*
* Generates the following HTML (sans formatting):
*
* <form method="post" action="/feeds/destroy/3" class="button-to">
* <div><input onclick="return confirm('Are you sure?');" value="Destroy" type="submit" /></div>
* </form>
*
* Note: This method generates HTML code that represents a form.
* Forms are "block" content, which means that you should not try to
* insert them into your HTML where only inline content is expected.
* For example, you can legally insert a form inside of a <div> or
* <td> element or in between <p> elements, but not in the middle of
* a run of text, nor can you place a form within another form.
* (Bottom line: Always validate your HTML before going public.)
