Katabatic 3 Modifications
=========================
General Structuration
=====================
* Short-circuit the usage of the Hurricane DataBase. Now AutoContacts
& AutoSegments are cached directly in the relevant objects. This is
way bigger, but should be faster. And anyway simpler to write by
suppressing Ring walkthrough and Session::lookup() calls.
AutoContact
===========
* Now splitted in four sub-classes:
* AutoContactTerminal
* AutoContactTurn
* AutoContactHTee
* AutoContactVTee
* isCorner() renamed isTurn().
* isTerminal() is now ambiguous. It may be flag an AutoContact which *is*
an AutoContactTurn indeed or an AutoContactTurn leading uniquely toward
a Terminal.
AutoHorizontal/AutoVertical
===========================
* New AutoSegment::makeTopologyDogLeg() creates dogleg needed by topological
adjustments on AutoContact. They are not counted (nor signaled) as explicit
dogleg request. **To Implement**.
* The local ``slacken()`` methods are, in fact AutoSegment::makeTopologyDogLeg().
* We now must be able to create AutoHorizontal/AutoContact whithout suppling
the anchor AutoContacts. Allows more supple building constructions.
