Column names themselves may contain data that should be included in each record. For example VCF files have a column name that is a Lab Number and it should be included on all records.

In order to store the column name in each record, include the map_columname_to key at the column level, with the value being the desired field and rawtext name.

Example mapping

- column: column_one
  mappings:
  - field: field_one
- column: abc123
  map_columname_to: 'columnname_field'
  mappings:
  - field: field_two

Example data:

"column_one","abc123"
"one","two"

This would result in:

{ 'field_one' => 'one',
  'columnname_field' => 'abc123',
  'field_two' => 'two',
  rawtext: { 'column_one' => 'one', 'abc123' => 'two', 'columnname_field' => 'abc123' } }
