gpio.read() api put the pin into input mode.

Maybe this should be added as a comment in the "Manipulate hardware like a arduino" example on https://github.com/nodemcu/nodemcu-firmware

Like the example is currently written it makes one think that one can read the state of the output pin which was set in the preceding line.

Here is a patch for that: https://github.com/jrahlf/nodemcu-firmw ... 3c3a58b7b7

I tested it and it works fine.
