title: Capitalize a string
body: <p>Does anyone know of a really simple way of capitalizing just the first letter of a string, regardless of the capitalization of the rest of the string?</p>
  
  <p>For example:</p>
  
  <pre><code>asimpletest -&gt; Asimpletest
  aSimpleTest -&gt; ASimpleTest
  </code></pre>
  
  <p>I would like to be able to do all string lengths as well.</p>
