[python] Fork of the suffix-array extractor with surface improvements

Available as the cdec.sa module, with commande-line helpers:
python -m cdec.sa.compile -f ... -e ... -a ... -o sa-out/ -c extract.ini
python -m cdec.sa.extract -c extract.ini -g grammars-out/ < input.txt > input.sgml

+ renamed cdec.scfg -> cdec.sa

+pycdec is a Python interface to cdec
+
+## Installation
+
+pycdec depends on the configobj module:
+
+	pip install configobj
+
+Build and install pycdec:
+
+	python setup.py install
+
+## Grammar extractor
+
+Compile a parallel corpus and a word alignment into a suffix array representation:
+
+	python -m cdec.sa.compile -f f.txt -e e.txt -a a.txt -o output/ -c extract.ini
+
+Extract grammar rules from the compiled corpus:
+	
+	cat input.txt | python -m cdec.sa.extract -c extract.ini -g grammars/
+
+This will create per-sentence grammar files in the `grammars` directory and output annotated input suitable for translation with cdec.
+	
+## Library usage
+
+A basic demo of pycdec's features is available in `test.py`
+
+More documentation will come as the API becomes stable.

+"""This module implements a partial stratified tree (van Emde Boas, 1977).
+Only insert findsucc, __iter__, and __contains__ are implemented.
+Delete is currently not supported.
+There is very little error-checking in this code -- it is designed
+to be used in the limited situation described in Lopez (EMNLP-CoNLL 2007),
+which doesn't cover all of the possible ways that you could misuse it
+(e.g. trying to insert a key larger than the universe size)
+Other notes -- this code is really rather ugly C code masquerading as
+Pyrex/Python.  Virtual function calls are bypassed by hand in several
+places for the sake of efficiency, and other Python niceties are 
+removed for the same reason."""
