title: Make all fields required in Mongoose
body: <p>Mongoose seems to default to make all fields not required. Is there any way to make all the fields required without changing each of:</p>
  
  <pre><code>Dimension = mongoose.Schema(
    name: String
    value: String
  )
  </code></pre>
  
  <p>to</p>
  
  <pre><code>Dimension = mongoose.Schema(
    name:
      type: String
      required: true
    value: 
      type: String
      required: true
  )
  </code></pre>
  
  <p>It'll get really ugly since I have a lot of these.</p>
