increased shadow map texture resolution--wasn't looking too good on the nvidia pc (supposedly there are some weird bugs on nvidia cards--need to check the workarounds.)
added some logging logic within the Trial class.  Currently just prints to console, but will work with CSV Writer when ready to be added.
now logs to an actual file.  Still needs headers, trial numbers, trial times info, though.
experiment time, trial time, handler names (for reference), and headers all added, plus filenames are automatically appended with a timestamp.
logfiles now write the docstring of all called functions in the experiment, to promote interpretation of the log.
