Add gui ds

Added GUIDs to the data/biology/suveys.csv data set and related files. Changed the name of the id field in surveys.csv from "record_id" to "survey_id" because the id is not identifying the record, it is identifying the survey. Updated the SQL and R lessons to refer to the updated column name and data. Did not change R files under the lessons/R/distributed and lessons/R/materials directories. Did not update Python lesson.
