Minor proofreading things.
Debug inflate code.
Debug changes to serial path.

The trick for detecting the path via the manufacturer doesn't seem to work as reliably for the Uno.  I'm working on it.
Hooked up the pulse sensor.

Now to integrate this with the new version of the code.
Merge branch 'master' into debug_inflate

Conflicts:

Using d3 linear range to set blowfish height.

Assuming successful readings from the pulse sensor, it sets the fish height according to the range.

Possible next steps: different range depending on the fish size, smoother Y transition.
Connected Wesley's finale code.

This only runs when not in debug mode: I'm assuming that if we are in debug mode, we probably want to keep testing.
Port-locating code that supports the Uno.

- For some reason, the Uno gives back port names starting with 'cu' instead of 'tty'.  Fix this.
- Changed logging to diagnose pulse sensor issues.
