<p>
          A [multi]set_of set view is a std::[multi]set signature-compatible interface
          to the underlying heap of elements contained in a <code class="computeroutput"><span class="identifier">bimap</span></code>.
        </p>
<p>
          There are two variants: set_of, which does not allow duplicate elements
          (with respect to its associated comparison predicate) and multiset_of,
          which does accept those duplicates. The interface of these two variants
          is largely the same, so they are documented together with their differences
          explicitly noted where they exist.
        </p>
<p>
          If you look the bimap from a side, you will use a map view, and if you
          look at it as a whole, you will be using a set view.
