Column names

Most functions in this package will take column names (*_col) as optional arguments (otherwise a default column names are used) which are then used as templates to find all other columns with the same field number, but different instance and array numbers. These functions will automatically find all matching instances (and arrays within each instance) within the specified parameters. Internally, a set of expand_instance_*() helper functions, which themselves rely on the column_expansion_helper() function, perform the work of searching for matching columns.
