Stub array interfaces from an existing array.

[courtney-miles]

This PR is for #905

It provides a convenient way to stub all the methods associated with a class that implements \Iterator, \ArrayAccess or \Countable, by supplying an array as the source for the method values.

$arrOfViolations = [
    \Mockery::mock(\Symfony\Component\Validator\ConstraintViolationInterface::class),
    \Mockery::mock(\Symfony\Component\Validator\ConstraintViolationInterface::class),
];

$mockViolationList = \Mockery::stubTraversable(
    \Symfony\Component\Validator\ConstraintViolationListInterface::class,
    $arrOfViolations
);

echo count($mockViolationList); // 2

foreach ($mockViolationList as $violation) {
    // ...
}

A con with this current implementation is that the array items can't be updated. I.e. it does not stub ArrayAccess::offsetSet() and ArrayAccess::offsetUnset()

Is this a limitation of Mockery or just this specific implementation?

I wonder if most of the logic here could be pulled in to it's own class? The Container class is quite a monster as is and I can't see that the code needs to live there.

There was an issue with my implementation. I don't recall exactly what the issue was, but I wanted to see if there was interest in this before I invested in finding a solution.

I'm happy to shift it.

Stay tuned for the next update.
