title: Regex for validating postcode and phone number
body: <p>I am creating a form, with warning elements. All works great but need to define my patterns better.</p>
  
  <pre><code>                $("#postcode").inputNotes( 
                {
                  warning: {
                    pattern: /^[0-9]+$/,
                    type: 'note',
                    text: 'Only numbers, please ...',
                    inversedBehavior: true
                  }
                }
              );
              $("#phone").inputNotes( 
                {
                  warning: {
                    pattern: /^[0-9]+$/,
                    type: 'note',
                    text: 'Only numbers, no spaces please ...',
                    inversedBehavior: true
                  }
                }
              );
  </code></pre>
  
  <p>Ok for the Postcode warning, I want the pattern to expect 4 numbers</p>
  
  <p>For the Phone warning, I want the pattern to expect 10 numbers.</p>
  
  <p>Any help appreciated.</p>
