+ IQv2 supports a <code>RangeQuery</code> that allows to specify
unbounded, bounded, or half-open key-ranges. Users have to use
<code>withUpperBound(K)</code>, <code>withLowerBound(K)</code>,
+ or <code>withNoBounds()</code> to specify half-open or unbounded ranges,
but cannot use <code>withRange(K lower, K upper)</code> for the same.

closes this gap by allowing to pass in <code>null</code>
+ as upper and lower bound (with semantics "no bound") to simplify the
usage of the <code>RangeQuery</code> class.
