function field_example_field_schema

Implements hook_field_schema().

Defines the database schema of the field, using the format used by the Schema API.

The data we will store here is just one 7-character element, even though the widget presents the three portions separately.

All implementations of hook_field_schema() must be in the module's .install file.
