title: Refactor "package structure" in Eclipse to relocate a package's child package to its parent package
body: <p>In Eclipse's "Package Explorer", let's say I have a list of packages like this:</p>
  
  <ul>
  <li>com.animal.dog </li>
  <li>com.animal.cat</li>
  <li>com.animal.frog</li>
  </ul>
  
  <p>If I want to refactor this package structure so that the final package structure looks like</p>
  
  <ul>
  <li>com.dog </li>
  <li>com.cat</li>
  <li>com.frog</li>
  </ul>
  
  <p>So essentially removing the parent package &amp; attaching the child packages to its grandparent. I have many child packages in "com.animal" package &amp; I would like to avoid if possible doing this manually &amp; then also changing the package imports everywhere.</p>
