Got to-short-array working
Got audio input working with 16 bit depth
listen-for-barks seems to be basically working with timestamps
Added .DS_Store files to gitignore
Listen-for-barks can read from a wav in addition to the mic.
Moved from a timestamp-based method of representing a bark to a
buffer-based system (where a buffer is 1/10th of a second). I still
include a timestamp marking the start of each bark so I can query
on the barks within a recording on the server side (if that's where I
land)
