title: Regular Expression - letters, apostrophes, full stops, commas and hyphens are allowed
body: <p>I am scratching my head around for this small yet confusing requirement that I have.</p>
  
  <p>I need a regular expression for the name field which only allows letters, apostrophes, full stops, commas and hyphens. Name field also should not allow more than 150 characters.</p>
  
  <p>Any help would be much appreciated!</p>
