Compiles and renders a Handlebars template string in a single step.

If you'll be using a template more than once, it's more efficient to compile it
into a function once using `compile()`, and then render it whenever you need to
by simply executing the compiled function. However, if you only need to compile
and render a template once, `render()` is a handy shortcut for doing both in a
single step.

@example

    Y.Handlebars.render('The pie of the day is {{pie}}!', {
        pie: 'Maple Custard'
    });
