title: Ionic3 set default when generate new page
body: <p>I would like to know how to set default import in the .ts file when i use CLI to generate a new page.</p>
  
  <p>Example: I want to add additional import for my shared function:</p>
  
  <p><code>import { SharedFunctions } from '../functions/sharedFunctions.ts'</code></p>
  
  <p>As well as set the default constructor like:</p>
  
  <pre><code>constructor(public sharedFunctions:SharedFunctions ){
  //... other codes
  }
  </code></pre>
  
  <p>Thank you.</p>
