body: <p>How to get the most frequent row in a DataFrame?
  For example, if I have the following table:</p>
  <pre><code>   col_1  col_2 col_3
  0      1      1     A
  1      1      0     A
  2      0      1     A
  3      1      1     A
  4      1      0     B
  5      1      0     C
  </code></pre>
  <p>Expected result:</p>
  <pre><code>   col_1  col_2 col_3
  0      1      1     A
  </code></pre>
  <p>EDIT: I need the most frequent row (as one unit) and not the most frequent column value that can be calculated with the <code>mode()</code> method.</p>
