[BioPython] Questions regarding different modules

[Andreas Kuntzagk]

Hi,

after working with some of the biopython code for quite some time I
started to get an overview of all the other modules out there.

Now I've got some questions:

- I could not understand the purpose of Decode.py
- Whats the purpose of Bio.GA, Parsers, SVDSuperimposer, Search?
- Is Bio.expressions obsolete (seems to contain older versions of the 
  regular expressions for the various formats)?
- What means "trie" in triefind? I could not find it in my dictionary,
  but assume it should be "tree"?

Please excuse if some of my Questions seem stupid. ;-)
