This is required for Auto Format compatibility because it has the undesirable effect of indenting only unindented contents of multi-lline comments, thus altering the relative indentation of the text.
The exception is the Max/MSP patches as I did not know whether indentation would break them.
Tools > Auto Format in the Arduino IDE removes asterisks from the start of every line in a C style comment, causing that character to be unsuitable for use as a bullet for lists in the example comments.
Renamed Leonardo Only examples folder to USB. Modified keyboard and
Mouse examples to indicate Due compatibility.
Minor modifications to Due examples to conform with existing example
sketches.
Added keywords to for Audio, Scheduer, and USBHost libraries.
