Add more advanced debug macro
Make it possible to have multiple debug levels. This makes it possible
to remove unneeded (debug) output when user is not interested in
seeing the output.

Add draw_plots.sh
This simple helper script draws all plots for a given logfile. The
.plot files are adjusted to not use a fixed file name, but instead
rely on the calling script to set the file into "datafile" variable.

main: Fix busy loop with reading
As the baud.c opens the serial device with O_NBLOCK flag, read will
just return immediately when there is nothing to read. That basically
makes the read loop a a busy loop, consuming one CPU core fully at all
times.
Fix the problem by using epoll to wait until something becomes
available on the serial port to read.

Add couple of example gnuplot files for plotting graphs
voltage_and_current.plot: This one plots somewhat typical charging
graphs with voltage, current and accumulated charge visible.
balancing.plot: This one plots a graph of the balancing action. Cell
voltages compared to the average cell voltages (over average of five
samples) is plotted.

Initial commit
Add a very very simple version of the "plotter". It does no plotting,
it only opens the serial device with correct baud rate, reads out the
data at correct baud rate (correct for an iCharger 206B charer) and
prints out exactly what it read. Dumb as hell but works.
