/**
 * 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
