List Defind (mostly) Auger Bit Tray

This is a list defined Auger Bit tray. It is not completely list defined as I hacked it to hold the larger cutter for the adjustable bit, and the plastic saving cutout, only works for Auger bits.
The alternative design I have included for the brace screwdriver bits is purely list defined.

Each bit is defined as a series of diameters and lengths with a conic section starting and ending at the diameters, the specified length apart. The list of diameters and lengths ends with a zero diameter.

This allows the description of a large number of solids of rotation.

I'm kind of ambivalent about this one. While it keeps the bits organized, it takes more space in by drawer than the loose bits do.
