DataFile should be able to read file contents without caching the entire data set.

Steps to implement:

Change constructor to simply store the path (and maybe validate it).
Change getStream methods.
Option A. Change the getStream methods to skip to the required section, read it into a collection, and return it.
Option B. Change the get*Stream methods to return a Stream-wrapped Iterable that only loads one record at a time.
