Tiny little bit of documentation would not hurt

Hi guys!

I'm trying to use your library, in my case for servo control.
Some functions you are using in your examples - I don't understand.
Specifically I have no idea what is setupOutputEnablePin and enableOutputs for.
A bit of comments would help.

I'm sure I could figure it out by reading the code and then reading the specs, but who has time for that :)
Overall, thanks for the library!

Thanks,
Mike K

Yes good point, I should add some more documentation. Until then I will add the PCA9685 datasheet to the repository. If you look at the datasheet, you will see that the chip has an enable input. The outputs of the chip are only enabled when this input is LOW. You can either tie the input to the chip LOW permanently when you wire up the chip or you can wire up that chip input to an output pin on your microcontroller and pull it LOW using these library functions or your own code.
