Add callback functions/filters

[izonder]

Now I can do this in config file:

'viewRenderer' => array(
    'class' => 'ext.ETwigViewRenderer',
    'functions' => array(
        'route' => function($route) { 
            return Yii::app()->urlManager->createUrl($route);
        }
    )
),

How can you use this afterwards? Should be documented.

[izonder]

It's used as usual:

<a href="{{ route('site/index') }}">Home</a>

Yet another example of using:

'viewRenderer' => array(
    'class' => 'ext.ETwigViewRenderer',
    'filters' => array(
        't' => function($message, $options = array(), $category = 'app'){
            return Yii::t($category, $message, $options);
        }
    ),
),

This will define the 't' filter for i18n. Than you can use:

<a href="#">{{ 'Click here'|t }}</a>

Looks very useful. Can you add it to readme?

@izonder, I think, you should also add some info/example about PHP functions wrapper.

One space after // would be nicer.
