/// The format of the fieldName keys will be "customField_FOO_field_name_with_underscores",
/// where FOO is one of "entry", "senses", or "examples". <br />
/// Some fields have no need for a GUID (e.g., a custom number field), so not all fieldNames will appear in customFieldGuids.
/// Only custom fields with actual data will be returned: empty lists and strings will be suppressed, and integer
/// fields whose value is 0 will be suppressed. (They will get the default int value, 0, when read from Mongo, so this
/// allows us to save space in the Mongo DB). If a custom field's value is suppressed, it will not appear in the output,
/// and will not have a corresponding value in customFieldGuids.
/// If ALL custom fields are suppressed because of having null, default or empty values, then this function will return
/// null instead of returning a useless-but-not-actually-empty BsonDocument.
