Message:

Genetics reorganization (affects ALL applications!):

• Converters/Validators? are now configured/initialized in a more verbose but also less confusing way
• At the same time, the PreconfiguredGenetics? object will help you avoid the increased complexity by creating the ready-to-use environment that is sufficient in 99% of cases (see the demos)
• Format F genetics updated (work in progress)
