| This example shows how to construct a bidirectional map with multi_index_container. |
| By a bidirectional map we mean a container of elements of <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">pair</span><span class="special"><</span><span class="keyword">const</span> <span class="identifier">FromType</span><span class="special">,</span><span class="keyword">const</span> <span class="identifier">ToType</span><span class="special">></span></code> such that no two elements exists with |
| the same first or second value (<code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">map</span></code> only |
| guarantees uniqueness of the first member). Fast look-up is provided for |
| both keys. The program features a tiny Spanish-English dictionary with on-line |
| query of words in both languages. |
