Allow queries to be printed

[GoogleCodeExporter]

From forum: https://groups.google.com/forum/#!topic/cqengine-discuss/xhpeTIH0uh0

It should be possible to print queries for debugging purposes.

toString should be implemented consistently across all Query objects.

Original issue reported on code.google.com by ni...@npgall.com on 27 Aug 2013 at 11:03

Fixed in trunk.

The code:

    Query<Car> query = and(
        equal(Car.MANUFACTURER, "Toyota"),
        equal(Car.COLOR, Car.Color.BLUE),
        equal(Car.DOORS, 3)
    );

    System.out.println(query);

Now prints:

    and(equal(Car.manufacturer, Toyota), equal(Car.color, BLUE), equal(Car.doors, 3))

The toString representation of queries, now resembles the representation of 
those queries in code (i.e. as constructed using QueryFactory). There is still 
some work to be done for toString representation of JOINs.

I'll leave this ticket open until this fix has been released to Maven central.
