This class is loosely based on the Lucene (java implementation) demo class
org.apache.lucene.demo.IndexFiles. It will take a directory as an argument
and will index all of the files in that directory and downward recursively.
It will index on the file path, the file name and the file contents. The
resulting Lucene index will be placed in the current directory and called
'index'.
