Parsers is just a directory to hold spark.py, which is used to parse
GenBank locations.

Not obsolete, but incomplete.  That's the basis of code that will
auto-detect different file formats and automatically choose a parser
for your file format.  The expressions in there need to be filled out
somewhat.

It's a data structure for efficiently storing strings that might have
common prefixes, e.g. an english dictionary:
http://www.nist.gov/dads/HTML/trie.html

Hope that helps!
