This change alters the functionality of getObjectAttr slightly: it no
longer accepts null or Array objects as "object" values.  I made this
change because the type checking code seems designed to mirror the
semantics of JSON, where each value belongs to exactly one of the
following categories: array, boolean, number, null, object, or string.

This change also changes the type of values thrown from strings to Error objects so that there are more likely to be useful stack traces when an error occurs.
