/**
*
* A class that defines how the client sees the data for a mapped field, i.e., a
* field that simply gets copied from an actual field in the row data, as is with
* start and end delimiters trimmed. This is needed because the db returns
* schema, pk, and fk names with delimiter chars.
* Note that this FieldMap is designed only for strings.
* Note that the field index may be different than the field that this is
* representing.
*
*
* For example, a field comes as the 3rd column, but we need to map it to the
* 5th column.
