Unconditionally close a <code>Closeable</code>.
<p>

This is typically used in finally blocks.

Example code:
<pre>
  Closeable closeable = null;
  try {
      closeable = new FileReader("foo.txt");
      // process closeable
      closeable.close();
  } catch (Exception e) {
      // error handling
  } finally {
      IOUtils.closeQuietly(closeable);
  }
</pre>
