Pins in the comments of the code

[Palmstroemen]

Just want to suggest adding one or two comment lines to the top of the code of the examples. Something like:
// Pins for most Arduinos: SDA=A4, SCL=A5
// Differs for some boards like i.e. Mega 2560: SDA=20, SCL=21, ...
// Look for hardware I2C-Pins on your board!

It took me some time to figure that out. Pins are often described in the comments of example sketches.
