title: How to prefix file names when using grunt assemble
body: <p>I have returned this question to its original form so that is more readable for future readers.</p>
  
  <p>I have some grunt-assemble tasks in my <code>Gruntfile.js</code></p>
  
  <pre><code>assemble: {
          options: {
              flatten: true,
              layoutdir: 'test-templates/meta_test_templates',
              partials: [
                  'test-templates/general_includes/**/*.hbs', 
                  'test-templates/users/**/*.hbs', 
                  'test-templates/content/**/*.hbs'] 
          },
          webmaster_crud: {
              options: { layout: 'webmaster_crud.hbs' },
              dest: '../compiled-tests/content/webmaster/',
              src: ['test-templates/content/content_types/*.hbs']
          }
  }
  </code></pre>
  
  <p>I want to prefix each of the output files with the word <code>webmaster</code></p>
  
  <p>So the output would be:</p>
  
  <pre><code>/compiled-tests/content/webmaster/webmaster_file1.html
  /compiled-tests/content/webmaster/webmaster_file2.html
  etc
  </code></pre>
  
  <p>The packages installed in my package.json file</p>
  
  <pre><code>"devDependencies": {
      "assemble": "^0.7.3",
      "grunt": "^0.4.5",
      "grunt-assemble": "^0.4.0",
      "grunt-contrib-clean": "^0.7.0"
  }
  </code></pre>
  
  <p>UPDATE 19/1/16
  I have included the entire assemble object passed to my grunt.initConfig and I have included the dependencies in package.json.</p>
  
  <p>UPDATE 12/1/16
  uncommented <code>expand</code> command and included ensuing error message</p>
  
  <p>UPDATE 12/1/16
  have returned the question to its original form sans the additional bug I discovered when not including the path variable in the function. </p>
