The nav_link helper

Drop nav_link_helper.rb into app/helpers in your Rails app and enjoy.

The nav_link helper works just like the standard Rails link_to helper, but adds a 'selected' class to your link (or its wrapper) if certain criteria are met. By default, if the link's destination url is the same url as the url of the current page, a default class of 'selected' is added to the link.

###Basic Example If the url of the current page matches the url of the link (http://example.com/page),

<%= nav_link 'My_Page', 'http://example.com/page' %>

	#main {
	width: 70%;
	padding: 2%;
	}

	th.field_heading_version a {
	color: #DD4B39;
	}

	li.tab_time_tracking a {

	/* @group SCSS Grid */

	$column-width: 45px;
	$gutter-width: 16px;

	@mixin col-width($span){
	width: ($column-width + $gutter-width) * $span - $gutter-width;
	}

	@mixin col-offset($span){
