<p>For every perpandicular set of AutoSegment to the <a class="el" href="classKite_1_1TrackSegment.html" title="Derived Katabatic::AutoSegment for the router. ">TrackSegment</a> we want to place, get the coordinates of the extremity not connected to the segment and put that coordinate into a table associated with it's <em>spin</em>. The <em>spin</em> tells if the extremity is attracting the segment <em>up</em> or <em>down</em> (for an horizontal segment). The <em>spin</em> is incremented for up and decremented for down. After all the extremities have been processeds, we took into account only the coordinates with a non-zero spin, which means they truly attract the segment (whatever the direction).</p>

<p>Main changes in <a class="el" href="classKite_1_1DataNegociate.html" title="Algorimthmic datas associated the TrackSegment. ">DataNegociate</a> class design:</p><ul>
|
|
<li>Merge in the separate class <code>Cost</code>.</li>
|
|
<li>Suppress the <code>SlackState::Desalignate</code>, due to the simplificated structure of the AutoSegment/AutoContacts (no more collapseds, or forced alignements). </li>
