-	 * Creates a debounced function that delays invoking `func` until after `wait`
-	 * milliseconds have elapsed since the last time the debounced function was
-	 * invoked. The debounced function comes with a `cancel` method to cancel
-	 * delayed `func` invocations and a `flush` method to immediately invoke them.
-	 * Provide `options` to indicate whether `func` should be invoked on the
-	 * leading and/or trailing edge of the `wait` timeout. The `func` is invoked
-	 * with the last arguments provided to the debounced function. Subsequent
-	 * calls to the debounced function return the result of the last `func`
-	 * invocation.
-	 *
-	 * **Note:** If `leading` and `trailing` options are `true`, `func` is
-	 * invoked on the trailing edge of the timeout only if the debounced function
-	 * is invoked more than once during the `wait` timeout.
-	 *
-	 * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
-	 * until to the next tick, similar to `setTimeout` with a timeout of `0`.

+	//  This file does nothing on ES5 systems.
+	//      JSON.stringify(value, replacer, space)
+	//          value       any JavaScript value, usually an object or array.
+	//          replacer    an optional parameter that determines how object
+	//                      values are stringified for objects. It can be a
+	//                      function or an array of strings.
+	//          space       an optional parameter that specifies the indentation
+	//                      of nested structures. If it is omitted, the text will
+	//                      be packed without extra whitespace. If it is a number,
+	//                      it will specify the number of spaces to indent at each
+	//                      level. If it is a string (such as "\t" or "&nbsp;"),
+	//                      it contains the characters used to indent at each level.
+	//          This method produces a JSON text from a JavaScript value.
+	//          When an object value is found, if the object contains a toJSON
+	//          method, its toJSON method will be called and the result will be
+	//          stringified. A toJSON method does not serialize: it returns the
+	//          value represented by the name/value pair that should be serialized,
+	//          or undefined if nothing should be serialized. The toJSON method
+	//          will be passed the key associated with the value, and this will be
+	//          bound to the value.
+	//          For example, this would serialize Dates as ISO strings.
+	//              Date.prototype.toJSON = function (key) {
+	//                  function f(n) {
+	//                      // Format integers to have at least two digits.
+	//                      return (n < 10)
+	//                          ? "0" + n
+	//                          : n;
+	//                  }
+	//                  return this.getUTCFullYear()   + "-" +
+	//                       f(this.getUTCMonth() + 1) + "-" +
+	//                       f(this.getUTCDate())      + "T" +
+	//                       f(this.getUTCHours())     + ":" +
+	//                       f(this.getUTCMinutes())   + ":" +
+	//                       f(this.getUTCSeconds())   + "Z";
+	//              };
+	//          You can provide an optional replacer method. It will be passed the
+	//          key and value of each member, with this bound to the containing
+	//          object. The value that is returned from your method will be
+	//          serialized. If your method returns undefined, then the member will
+	//          be excluded from the serialization.
+	//          If the replacer parameter is an array of strings, then it will be
+	//          used to select the members to be serialized. It filters the results
+	//          such that only members with keys listed in the replacer array are
+	//          stringified.
+	//          Values that do not have JSON representations, such as undefined or
+	//          functions, will not be serialized. Such values in objects will be
+	//          dropped; in arrays they will be replaced with null. You can use
+	//          a replacer function to replace those with JSON values.
+	//          JSON.stringify(undefined) returns undefined.
+	//          The optional space parameter produces a stringification of the
+	//          value that is filled with line breaks and indentation to make it
+	//          easier to read.
+	//          If the space parameter is a non-empty string, then that string will
+	//          be used for indentation. If the space parameter is a number, then
+	//          the indentation will be that many spaces.
+	//          Example:
+	//          text = JSON.stringify(["e", {pluribus: "unum"}]);
+	//          // text is '["e",{"pluribus":"unum"}]'
+	//          text = JSON.stringify(["e", {pluribus: "unum"}], null, "\t");
+	//          // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
+	//          text = JSON.stringify([new Date()], function (key, value) {
+	//              return this[key] instanceof Date
+	//                  ? "Date(" + this[key] + ")"
+	//                  : value;
+	//          });
+	//          // text is '["Date(---current time---)"]'
+	//      JSON.parse(text, reviver)
+	//          This method parses a JSON text to produce an object or array.
+	//          It can throw a SyntaxError exception.
+	//          The optional reviver parameter is a function that can filter and
+	//          transform the results. It receives each of the keys and values,
+	//          and its return value is used instead of the original value.
+	//          If it returns what it received, then the structure is not modified.
+	//          If it returns undefined then the member is deleted.
+	//          Example:
+	//          // Parse the text. Values that look like ISO date strings will
+	//          // be converted to Date objects.
+	//          myData = JSON.parse(text, function (key, value) {
+	//              var a;

+	//                          +a[5], +a[6]));
+	//                  }
+	//              }
+	//              return value;
