public static void closeQuietly(OutputStream output) {
        closeQuietly((Closeable) output);
    }
Unconditionally close an <code>OutputStream</code>.
<p>
Equivalent to {@link OutputStream#close()}, except any exceptions will be ignored.
This is typically used in finally blocks.
<p>
Example code:
<pre>
byte[] data = "Hello, World".getBytes();

OutputStream out = null;
try {
    out = new FileOutputStream("foo.txt");
    out.write(data);
    out.close(); //close errors are handled
} catch (IOException e) {
    // error handling
} finally {
    IOUtils.closeQuietly(out);
}
</pre>

@param output the OutputStream to close, may be null or already closed
