Example definition for use in testing API below ("Visits per visitor"):

"definition": {
      "formula": {
        "func": "divide",
        "col1": {
          "func": "metric",
          "name": "metrics/visits",
          "description": "Visits"
        },
        "col2": {
          "func": "metric",
          "name": "metrics/visitors",
          "description": "Unique Visitors"
        }
      },
      "func": "calc-metric",
      "version": [
        1,
        0,
        0
      ]
    }

A calculated metric response will always include these default items:* id, name, description, rsid, owner*

Other attributes can be optionally requested through the 'expansion' field as defined/documented in the GET endpoints (see GET "/calculatedmetrics" or GET "/calculatedmetrics/{id}" for more documentation).
