Subject: [PATCH 1/6] - In MachiningLib -> FindSawing aggiunto parametro
 opzionale bConsiderCSimmEncumberance per considerare l'ingombro dell'asse C
 nel massimo materiale (default false). - In MachiningLib -> GetMachinings
 vengono ora raccolti i parametri utensile necessari per i VerifyTool, scritti
 direttamente nella tabella Machining.Tool. - Le lavorazioni possono essere
 ora ordinate per dimensioni utensile (Longest, Shortest, Biggest, Smallest)
 se passato l'apposito parametro SortingCriterion in FindMachining. Al momento
 implementato solo per FindSawing. - In HeadCut e Split, nei tagli verticali
 aggiuntivi, si usa ora BD.MAX_LEN_DICE come dimensione (era BD.MAX_DIM_DICE).
 - In LapJoint e LongCut implementata gestione seghe a catena multiple.

Subject: [PATCH 6/6] - Le lavorazioni possono essere ora ordinate per
 dimensioni utensile (Longest, Shortest, Biggest, Smallest). Al momento
 implementato solo per FindSawing. - Nello split con sega a catena ora si
 cerca di preferenza una lavorazione di tipo 'SawingForSplitting'. Se non
 trovata si cerca il tipo 'Sawing' come in precedenza. - In split con sega a
 catena aggiunta estensione start/end del percorso se utensile lungo, per
 evitare collisioni con il pezzo durante rotazione.
