EgtGeomKernel 1.6a4 :

- DistPointLine correnta per versore non normalizzato
- aggiunta GetGeoType a GeomDB e a GdbIterator
- in lettura NGE binari aggiunta protezione da contemporanea scrittura
- in PolyLine aggiunta funzione per inserimento punti onde raggiungere massima distanza
- aggiunto oggetto VolZmap per virtual milling (per ora vuoto)
- nuova versione file NGE 1009.
