* Implemented Eager Per Row debouncing algorithm. Good for when fingers can only press one row at a time (e.g. when keyboard is wired so that "rows" are vertical) * Added documentation for eager_pr * Ported ergodox_ez to eager_pr debouncing. * Removed check for changes in matrix_scan. * Added further clarification in docs. * Accidental merge with ergodox_ez * Small cleanup in eager_pr * Forgot to debounce_init - this would probably cause seg-faults.

Here are a few ideas
 | 
						|
 | 
						|
1) Global vs Per-Key vs Per-Row
 | 
						|
 * Global - one timer for all keys. Any key change state affects global timer
 | 
						|
 * Per key - one timer per key
 | 
						|
 * Per row - one timer per row
 | 
						|
 | 
						|
2) Eager vs symmetric vs asymmetric
 | 
						|
 * Eager - any key change is reported immediately. All further inputs for DEBOUNCE ms are ignored.
 | 
						|
 * Symmetric - wait for no changes for DEBOUNCE ms before reporting change
 | 
						|
 * Asymmetric - wait for different times depending on key-down/key-up. E.g. Eager key-down, DEBOUNCE ms key up.
 | 
						|
 | 
						|
3) Timestamp vs cycles
 | 
						|
 * old old old code waits n cycles, decreasing count by one each matrix_scan
 | 
						|
 * newer code stores the millisecond the change occurred, and does subraction to figure out time elapsed.
 | 
						|
 * Timestamps are superior, i don't think cycles will ever be used again once upgraded.
 | 
						|
 | 
						|
The default algorithm is symmetric and global.

Here are a few that could be implemented:
 | 
						|
 | 
						|
sym_g.c
 | 
						|
sym_pk.c
 | 
						|
sym_pr.c
 | 
						|
sym_pr_cycles.c 
 | 
						|
eager_g.c
 | 
						|
eager_pk.c
 | 
						|
eager_pr.c //could be used in ergo-dox!
