 * Operation
 *
 * An Operation is any manipulation of some data that produces some output;
 * it defines the type of analysis that is run, its inputs and outputs,
 * and other relevant information. An Operation can be as simple as selecting a subset
 * of the columns/rows of a matrix or running a large-scale processing job
 * that spans many machines and significant time.
