<p><b>The Ever Fragmenting Data Structure</b></p>
<p>All the transformations applied to the database, after it's initial building, can be reduced to making new doglegs (and layer changes). Another way to put it, is that no Tee is ever created after the initial stage. The consequence is that the segments are only fragmenting more and more (up to a certain limit). The aligneds sets are progessively broken apart as needed, and until there remains only one tee per set (the two segments on the aligned branch).</p>

<b>Dogleg Creation.</b> Mean breaking the segment in two. This operation is used to slacken the constraints on a segment or restore connexity on source/target contact after a layer change. The new segment is always created on the source. </li>
