* Filled in all the board control examples. Everything works except for
DAC.
* Moved test drawing scripts to drawing dir and renamed them and added
comments.
* Filled in all the image filter stuff. There are still some tests that
can be renamed, commented, and added to this folder. But, I will do that
later.
* Fixed motion detection thresholds.
* Fixed LCD script comments.
* Fixed BLE return value.
Tried to emulate Arduino's 11 folders... I'd perfer to have all the
shield scripts in one folder... but, that might not make sense. I don't
really want one script per folder however. So, I might merge some more
stuff in the future. I have a grand idea here that will become evident as
I work though the examples.
Anyway, the current structure is not final. It will be in flux for a
little while.
As for Git History, folder history is the best we're going to get. Git
and GitHub don't seem to deal with moves too well.
