examples:
```JavaScript
var mySpy = jasmine.createSpyObj("mySpy", { getAge: 55, getLanguage: "JavaScrizzle" });
var age = mySpy.getAge();
expect(age).toEqual(55);
expect(mySpy.getAge).toHaveBeenCalled();
```
Also does:
Add "isObject_" method to utils to make it easier for "createSpy" to support an array or object of stubs
- Will replace rake core_specs.
- Remove obsolete dependencies & files -- most of these were for build tasks we
are no longer using. Notably, rspec and spec_helper were deleted.
Move from embedded "fork" of jsHint to using grunt's jsHint module.
Cleaned ALL jsHint errors.
Added jasmine.util.isUndefined as alternative to extra careful protection against undefined clobbering
