This is an attempt to clean up the Micro Python API on the pyboard. Gpio functionality is now in the Pin object, which seems more natural. Constants for MODE and PULL are now in pyb.Pin. Names of some classes have been adjusted to conform to CamelCase. Other miscellaneous changes and clean up here and there.
