Create enclosing scope to capture entire normalization
Generate a main method for the normalization
Create a bundle for common classes and interfaces that will be accessed by the Norm inferred model
Simplify mapping parser rule to ease initial development (removed FieldExpression)
Rework of the input/output architecture and API (1st of many, I'm sure)
Implement some of the very basic logic for the inferred JVM model

This consists mostly of the generated code for the Normalization parser rule
Merge branch 'norm_main'
Minor grammar improvements/clean-up
