This patch first implements an iterator so that we can properly iterate over the elements of the object returned by the _getMethodNames function. Next, the recordTestCoverage function now checks to see if the file actually has methods before recording them. And finally, some formatting was done.

This is a modification to recordTestCoverage. It now gathers methods and the lines each span, uncovered lines, and now also places a version control block at the beginning of every artifact.
