mcilwain 4d2e0941f3 Add a custom logic framework to provide pluggable extensibility
To add additional logic for flow code, write custom classes that extend the existing custom logic classes (of which DomainCreateFlowCustomLogic is the first provided example), along with a class that extends CustomLogicFactory to provide instances of the new custom logic classes. Then configure the fully qualified class name of your new custom logic factory in ConfigModule.provideCustomLogicFactoryClass().
