Actions
-------
run <configfile>
Runs pebl based on params in config file.
runtask <picklefile>
Unpickles the file and calls run() on it.
<picklefile> should be a a pickled learner or task.
viewhtml <resultfile> <outputdir>
Creates a html report of the results.
<resultfile> should be a pickled pebl.result.
<outputdir> is where the html files will be placed.
It will be created if it does not exist.
