Overview

Needed a column representation that would allow user to specify attributes that are used for sample data choice for virtual attributes e.g. if you have an object_id column in the schema, but in model you have virtual proxy attribute methods to set it like my_object_id/my_object_id= then you need a way to specify that it should set my_object_id= with a string vs. number, etc.
