* Add ARRAY_SIZE and CEILING utility macros
* Apply a coccinelle patch to use ARRAY_SIZE
* fix up some straggling items
* Fix 'make test:secure'
* Enhance ARRAY_SIZE macro to reject acting on pointers
The previous definition would not produce a diagnostic for
```
int *p;
size_t num_elem = ARRAY_SIZE(p)
```
but the new one will.
* explicitly get definition of ARRAY_SIZE
* Convert to ARRAY_SIZE when const is involved
The following spatch finds additional instances where the array is
const and the division is by the size of the type, not the size of
the first element:
```
@ rule5a using "empty.iso" @
type T;
const T[] E;
@@
- (sizeof(E)/sizeof(T))
+ ARRAY_SIZE(E)
@ rule6a using "empty.iso" @
type T;
const T[] E;
@@
- sizeof(E)/sizeof(T)
+ ARRAY_SIZE(E)
```
* New instances of ARRAY_SIZE added since initial spatch run
* Use `ARRAY_SIZE` in docs (found by grep)
* Manually use ARRAY_SIZE
hs_set is expected to be the same size as uint16_t, though it's made
of two 8-bit integers
* Just like char, sizeof(uint8_t) is guaranteed to be 1
This is at least true on any plausible system where qmk is actually used.
Per my understanding it's universally true, assuming that uint8_t exists:

* Run qmk-format on core C files touched in this branch

This is based on feedback talking with crop_octagon about the device. Future trackballs will ship with ATMEL DFU for simplicity. This also includes some fixes and optimizations based on code review and tinkering on my own devices.
* Initial Commit for Ploopyco Trackball
This is a WIP at this point. Most of it compiles, but the SPI commands are non-functioning as they come from Arduino, so don't exist in LUFA
* Convert SPI commands from arduino to LUFA
But I have no idea if this is actually correct or not
* Update keyboard readme
* Clean up ploopyco trackball
* Update readme
* Update mouse key stuff
* last minutue cleanup
* Add caveat about scroll wheel
* Fixup to code
* Additional fixup
* Add movement multiplier
* Rename folders
* mid changes
* temp
* Got it working!!!!!
* Additional cleanup of code
* Make unused pin calls more compact
* Rotation info
* Add debouncing checks
* Make everything replaceable
* Add info.json
* Include ISP flashing info
* Better handling for user customization
* Reconfigure CPI stuff
* fix issues with debug printing
* Fix tiny scroll issue
* Add and update scroll code from ploopy mouse
* Update licensing
* Add PloopyCo Mouse
* Cleanup and layout stuff
* Move common files to main folder for reuse
* Increase polling rate
* Update image for mouse
* Apply changes from code review
* Add VIA support
