  /**
  Compiles a template string into a JavaScript function. Pass a data object to the
  function to render the template using the given data and get back a rendered
  string.
  
  Within a template, use `<%= ... %>` to output the value of an expression (where
  `...` is the JavaScript expression or data variable to evaluate). The output
  will be HTML-escaped by default. To output a raw value without escaping, use
  `<%== ... %>`, but be careful not to do this with untrusted user input.
  
  To execute arbitrary JavaScript code within the template without rendering its
  output, use `<% ... %>`, where `...` is the code to be executed. This allows the
  use of if/else blocks, loops, function calls, etc., although it's recommended
  that you avoid embedding anything beyond basic flow control logic in your
  templates.
  
  Properties of the data object passed to a template function are made available
  on a `data` variable within the scope of the template. So, if you pass in
  the object `{message: 'hello!'}`, you can print the value of the `message`
  property using `<%= data.message %>`.
  
  @example
  
      YUI().use('template-micro', function (Y) {
          var template = '<ul class="<%= data.classNames.list %>">' +
                             '<% Y.Array.each(data.items, function (item) { %>' +
                                 '<li><%= item %></li>' +
                             '<% }); %>' +
                         '</ul>';
