Support for directives

[calvinte]

I'd like to be able to add directives to expressions in a similar fashion to how modifiers are executed against values now. My particular use case (see code below) would be to support nested templates.

Template:

<strong>{{ list.name }}</strong>
<ul class="things">
  {% for thing in list.things|attachThings %}
    <li class="thing {{thing.class}}">
    </li>
  {% endfor %}
</ul>

Javascript:

var thingTemplate = 'Thing: {{thing.name}}';
var list = {
  name: 'Test List',
  things: [
    {name: 'testThing1', class: 'textThing1Class'},
    {name: 'testThing2', class: 'textThing2Class'}
  ]
}

Ashe.addDirectives({
  attachThings: function(values) {
    values.forEach(function(v) {
        // key `thing` equal to `thing` in loop.
        v.thing;
        // key `template` is `Array` containing elements inside loop,
        v.template;

        var element = $('.thing', template);
        var content = Ashe.parse(thingTemplate, thing);
        element.html(content);
    });
  }
  // , oneMoreDirective: function(values) { ... }
});

What are you thoughts on this being included in Ashe?

This looks nice. However I'm a little tight on time in the moment. So not sure if I will support Ashe at all. There are better options like Handelbars I believe.
