-// objAsString will try to return the provided object as a string. If the
-// object is already a string, it will be returned without modification. If the
-// object is an 'Error', the message of the error will be returned. If the object
-// has a toString method, the toString method will be called and the result
-// will be returned. If the object is null or undefined, a special string will
-// be returned indicating that the undefined/null object cannot be converted to
-// a string. In all other cases, JSON.stringify is used. If JSON.stringify
-// throws an exception, a message "[could not provide object as string]" will
-// be returned.
