/**
* Outputs a html &lt;a&gt; tag
* <pre>
* * href : the target URI where the link must point
* * rest : any other attributes you want to add to the tag can be added as named parameters
* </pre>
*
* Example :
*
* <code>
* {* Create a simple link out of an url variable and add a special class attribute: *}
*
* {a $url class="external" /}
*
* {* Mark a link as active depending on some other variable : *}
*
* {a $link.url class=tif($link.active "active"); $link.title /}
*
* {* This is similar to: <a href="{$link.url}" class="{if $link.active}active{/if}">{$link.title}</a> *}
