Wheel generator 1.6

I'd like to announce the availability of the new version of Wheel generator.
This version builds on the power of the 1.5 version and introduces several new exciting fetures. Among them are:
- Ability to construct filtered coverings.
- Unlimited number groups (formely common numbers).
- New filters: Distance, Positions, Low/High, Bankers
- A new detailed hits analysis with the ability to observe up to 2,1,0 hits! This is essential to know when playing with banker numbers.
- Improved building speed.
