+Debounce algorithms belong in this folder.
+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 assymetric
+ * 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
+ * Assymetric - 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:
+
+debounce_sym_g.c
+debounce_sym_pk.c
+debounce_sym_pr.c
+debounce_sym_pr_cycles.c //currently used in ergo-dox
+debounce_eager_g.c
+debounce_eager_pk.c
+debounce_eager_pr.c //could be used in ergo-dox!
