Utility to convert a subunit stream to an html results file.
Code is adapted from the pyunit Html test runner at
http://tungwaiyip.info/software/HTMLTestRunner.html
Takes two arguments. First argument is path to subunit log file, second
argument is path of desired output file. Second argument is optional,
defaults to 'results.html'.
