Slight difference between test example and actual test results

[nig66]

The usage example in the README file says;

$all = $jsonPointer->get("");

should yield;

'{"foo":1,"bar":{"baz":2},"qux":[3,4,5],"m~n":8,"a/b":0,"e^f":3}'

but in fact it yields;

'{"foo":1,"bar":{"baz":2},"qux":[3,4,5],"m~n":8,"a\/b":0,"e^f":3}'

So "a\/b" instead of "a/b".
