Mid checkin as I try to debug
Fixed issue with segfault; _deviceList is now allocated directly, and
instead points to the SetListDevice to avoid memory allocation issue.
Stable alpha release of SetListArduino

A working version as far as I can test in the serial console; attachInterrupt functionality still not tested and is currently commented out.

For details on what this library implements, including examples and a lengtly description, see the README.
Cleaned up code, deleted old fragments, and added doxygen-formatted documentation.
removed tmp.txt
Cleaned up library files, added documentation.

SetListArduino library should now be fully documented and set up to use
Doxygen.
Added template readme, still needs improvement.

README has basic structure, but needs some heavy editing and additional
documentation.
