Interesting. I wonder whether that was a result of the forward and  
reverse surgeries done to the Annotation* interfaces. (I'm off-line as  
I write this so can't check.)

get_all_Annotations() has always been recursive (similarly as  
get_all_SeqFeatures() is for SeqI). However, the recursive behavior is  
different from the behavior that Mira wants.

Specifically, if get_all_Annotations() finds a nested collection under  
a matching tag, it will consider the entire nested collection as  
match, and returns the recursively flattened out annotation objects it  
contains. What Mira needs (if I am understanding her implementation  
correctly) is recursively retrieving annotations if their tag matches  
the query key or set of keys. I.e., a nested collection would be  
searched for matching tags even if the tag of the collection itself  
does not match, and if it does match, only those of the contained  
annotations would be returned that have matching tags.

I'm not sure whether it's better to fold both behaviors into one  
method which has an optional argument to control which one is desired,  
or to have two methods. I'm leaning towards having two methods,  
because support for an added optional argument in external  
implementations of the interface is hard to test for, as opposed to  
testing for the presence/absence of a new method. On the other hand,  
if the existing method wasn't even on the interface to begin with  
(which I'm not yet convinced about) then that shouldn't really be an  
issue.

It seems Chris you are also for adding a second method (and putting  
get_all_Annotations() (back) into the interface)? Does anyone else  
have thoughts or preferences on this?
