Filter example on main JSONPATH page is incorrect

[GoogleCodeExporter]

See http://goessner.net/articles/JsonPath/

An example object and expression filters out any book that has a price greater 
than 10:

  $.store.book[?(@.price < 10)].title

This expression returns 4 titles, when it should return only 2 titles.

The correct expression is:

  $.store.book[?(@['price'] < 10)].title

...Running against jsonpath for PHP.
