variable asserter : missing documentation on isReferenceTo

[agallou]

Here is how I found to use the isReferenceTo method on the variable asserter :

$variable = new \ArrayObject(array('content'));
$reference = & $variable;

$variable2 = clone $variable;
$reference2 = & $variable2;

$this->variable->setByReferenceWith($reference)->isReferenceTo($variable); // pass
//$this->variable->setByReferenceWith($reference)->isReferenceTo($variable2); // fails

It seems weird to have to use the setByReferenceWith.

@jubianchi is it the right way to use it ?
