Finished writing the main part of the driver for the AMS/TAOS TSL2561 light sensor tonight. Could do with a few more helper functions and autoranging on the lux conversions, but for now it gives good readings.

Tested a few spots around my apartment and the readings appear reasonable. Will have to see if I can borrow the light meter from work sometime to confirm.
