/**
 * Validate a data set using a Lectern Schema. The data to validate is an array of DataRecords that contains all
 * records for the given schema. Each record of the data set will be validated individually, plus schema level
 * validation tests will be applied.
 *
 * Validation tests specific to Schema validation are:
 * - unique fields: for any fields marked as unique, this will check if there are multiple records with the same value
 * - uniqueKey: if the schema has a uniqueKey defined, this will check if there are multiple records with the same
 *   uniqueKey value
 *
 * @param records
