A parser in Scala

parts_parser.scala

/*
This is a version of a parser I wrote in Python for 
www.powerhousetoolparts.com. After reading about Case Classes and Pattern Matching,
I was wondering how nice it would be in Scala. And, while I don't 
cover all the edge cases, it's nice indeed.

The file has records like:
