[Soot-list] Mutable BlockGraph

[shmohtasham at gmail.com]

Thanks Eric.

Turns out that the list of blocks in BlockGraph is an  
"unmodifiableList" collection.
I found out about this when I got "UnsupportedOperationException" when
trying to call remove on the list returned from BlockGraph.getBlocks().

If what I observed is true, then writing a subclass of BlockGraph  
wouldn't
help either, because the list is immutable; unless the "buildBlocks"  
method is
overridden, which is probably the last thing I want to do :)
