+ * Takes a property path array, p, and a value, v, and returns an object to that spec.
+ *
+ * Example:
+ * objectify( ['foo', 'bar', 'baz'], [1, "42", {answer: 42}] )
+ *
+ * Would return an object literal in the form:
+ * {
+ *   foo: {
+ *     bar: {
+ *       baz: [1, "42", {"answer": 42}]
+ *     }
+ *   }
+ * }
+ *
+ * @param {array} p Deep property path, e.g. ['foo', 'bar', 'baz'] becomes foo.bar.baz
+ * @param {any} v Any JSON serialisable value to assign to the above property
