    Dynamic template module using version 2 of [ant](https://github.com/unkelpehr/ant).

    This module allows for {{ message.payload }}, and also {{# js code }}.
    The full message is accessible within template through message.property.

    Template can be set either through node config.template, or message.template.

    Example template:

        Welcome, {{ message.name }}!

        <ul>

        {{# message.payload.forEach(function(link) { }}
            <li><a href="{{ link.url }}">{{ link.text }} </a></li>
        {{# } }}

        </ul>
