Example execution:

1) Make sure the required files are available, wget files with:

 $ make files

2) Start by creating the SQLite database if it doesn't exist:

 $ runhaskell initDB.hs

3) Start ghci and collect identifiers for a package:

 $ ghci Conclave.hs 
 
 *Conclave> icollector p1

 p1 is a package definition available that includes the files downloaded
with make files.

4) Compute a rank for word 'name' for examples:

 *Conclave> rank <- locate "p1" "name"
 ID: username 	t1.c:2 	Similarity: 3.8081353
 ID: main 	t2.c:10 	Similarity: 0.10052833
 ID: main 	t1.c:16 	Similarity: 0.10052833
