Taking the tenets of the [Java style guide](http://google-styleguide.googlecode.com/svn/trunk/javaguide.html#s3.3.3-import-ordering-and-spacing) we are using, please move the io.prometheus imports above the third-party imports.

```
package io.prometheus.…;

import io.prometheus.…;

import third.party.foo;

import java.…;

```
