Added getters and setters for speed, power, time, step
Added getters and setters for ramp_UP, ramp_down, and steer
Got calculate_speed working, speed parameter can be read to get current motor speed. Still more cleanup needed. Next step is to get regulate_speed working
Speed regulation now works, instead of power, set target_speed. Next step is ramp up and ramp down to exact position
Motor drivers work reasonably well. Needs some cleanup around power vs speed and pin IDs
Cleaned up the GPIO pin names
Simplified attribute list, cleaned up code, and added position regulation. Next - clean up ramp modes
Motor driver is now ready for prime time - let\' merge it
Removed legoev3_motor.c - it is not used at all
Merge branch 'motor-driver' of github.com:mindboards/ev3dev-kernel
Merge branch 'master' of github.com:mindboards/ev3dev-kernel
