Detailed Description

Create comservatory::Field objects to capture column contents.

Instances of CsvFieldCreator subclasses can be passed to CSV validators like csv_data_frame::validate(). This allows the validator to execute user-defined code when parsing each column, typically to store the column's contents in a user-defined memory allocation. The contents can then be extracted for later inspection by the caller (e.g., in R or Python-managed vectors).
