@function

Returns YES if the passed object is an array or Array-like.

SproutCore Array Protocol:

- the object has an objectAt property
- the object is a native Array
- the object is an Object, and has a length property

Unlike SC.typeOf this method returns true even if the passed object is
not formally array but appears to be array-like (i.e. implements SC.Array)
