+ * @function compareAndRepeat
+ * This function compares results of two functions for multiple sets of arguments and then repeats  those calls to compare them with profiling.
+ * Testing showed that results are slightly skewed in favor of the secondaryProfileFunction, which (together with external factors)
+ * is almost compensated by running the calls often.
+ *
+ * @param {string} title - used for Debug output
+ * @param {function} profileFunction - function to compare
+ * @param {function} [secondaryProfileFunction] - secondary function to compare. Use falsy value to skip comparison.
+ * @param {Array.<Array.<*>>} [functionArgumentsArray = []] - argument sets to run both functions with
+ * @param {number} [testCount = 10000] - times to run each function in addition to result comparison
+ * @param {Object} [testContext = null] - If the functions use `this` or otherwise depend on a Closure/Execution context, it can be set here. If they, for example, use properties of a QML `Item`, you can use that `Item` as `testContext`.
+ *
+ * @example
+ * // to compare the results of Debug.log("first", "second", "third")
+ * // and Debug.log("some value")
+ * // with the same calls of console.log and run 100 times each:
+ * Functions.compareBenchmark("Debuglog",
+ *   Debug.log, console.log,
+ *   [["first", "second", "third"], ["some value"]],
+ *   100
