Laravel 4 HTML Macro to Generate Breadcrumbs

html-macro-breadcrumbs.php

/**
 * Laravel 4.1 HTML Macro to generate breadcrumbs!
 * 
 * Use it to generate breadcrumbs that compatible with Bootstrap 3.
 * 
 * To use it  you need to pass value through $arrayLinks with array that contains
 * named keys and it value. Key would be the label of breadcrumbs and value
 * would be the link. If we don't pass the named key then it would be label without
 * link attached. 
 * 
 * To customise home you may use "$homeLinks" with array that contains 'link' and 
 * 'label' as keys with it corresponding value.
 * 
 * Example:
 * 
 * $arrayLinks = array(
 *      'Post Index'=>route('post-index'),      // breadcrumb element to index
 *      'Editing ' . $post->title               // last elements of breadcrumbs
 * );
 * 
 * $homeLinks = array(
 *      'label' => 'Control Panel',             // change default index
 *      'link'  => route('control-panel')       // and it link
 * );
 * 
 * {{ HTML::breadcrumbs( $arrayLinks, $homeLinks ) }}
