/**
 * Create a unique string out of an arbitrary array of data record values. This can be used
 * as a unique identifier for an object with these properties and values. This type of hash is needed
 * to check uniqueKey constraints.
 *
 * To generate a unique string from an object, the object is converted to an array of [key, value] tuples.
 * Properties with an `undefiend` value are filtered out.
 * These tuples are sorted by key name to ensure they are compared in the same order.
 * Finally, the array is stringified using JSON.stringify().
 *
 * This can be used to compare uniqueKeys across many data records by building a map of the hash of
 * the uniqueKey values from each record.
 * @param values any DataRecord or subset of fields from a DataRecord
