title: Guess name from email
body: <p>Is there a standard or simple way to guess a name from an email address, similar to what gmail does?</p>
  
  <p>For example, "john.smith@whoever.com" should give "John Smith".</p>
  
  <p>Doing this shouldn't be too hard (strip domain name, remove special characters, capitalize, etc), but I'm sure there should be existing code for this.</p>
  
  <p>Code in Ruby would be preferred, but any other language would be fine.</p>
