docs: <p>
  Determines whether the target object is between min and max
  in value, this is, whether
  <tt>target.compareTo(min) &gt;= 0 &amp;&amp; target.compareTo(max) &lt;= 0</tt>.
  The target and the specified min and max have to implement {@link Comparable}.
  </p>
  
  @param min the minimum value of the target
  @param max the maximum value of the target
  @return true if the target is between min and max (or it's equal to any of them)
