title: gmock: Testing two float vectors
body: <p>I am trying to write a test for a vector.
  For STL containers, I tried:</p>
  
  <pre><code>EXPECT_THAT(float_vec1, ElementsAreArray(float_vec2));
  </code></pre>
  
  <p>However I need to insert a margin.</p>
  
  <p>Is there an <code>ElementsAreArray</code> equivalent of <code>FloatNear(a_float, max_abs_error)</code>?</p>
