TST: Test __array_priority__ for different class combinations.
TST: Test __array_priority__ for different class combinations.

This checks the four classes with different __array_priority__ values
against each other for the operators

    __add__, __radd__
    __sub__, __rsub__
    __mul__, __rmul__
    __pow__, __rpow__
    __div__, __rdiv__
    __mod__, __rmod__
    __truediv__, __rtruediv__
    __floordiv__, __rfloordiv__
    __and__, __rand__
    __xor__, __rxor__
    __or__, __ror__
    __lshift__, __rlshift__
    __rshift__, __rrshift__
    __eq__
    __ne__
    __gt__
    __ge__
    __lt__
    __le__

The classes are ndarray, two subclasses of ndarray, and a class unrelated
to ndarray. The combinations checked are

    ndarray -- ndarray subclass
    ndarray -- unrelated class
    ndarray subclass -- ndarray subclass
    ndarray subclass -- unrelated class
