First commit of windrain.ino.
windrain.ino is the wind and rain portion of wx.ino carved out into a seperate hardware unit.
Additionally, the link was changed from wireless to wired serial.
This version works well enough to be the first commit.
First commit of serialmaster.ino.
serialmaster.ino is a rethinking of the old ear.ino node.  Instead of listening
over wireless for a single node, it now uses software timed serial to switch between
two dedicated wired serial links to seperate weather station nodes.  One node is for
the wind and rain sensing cluster (anemometer, vane, and rain bucket), the other will
be for everything else (temp, humidity, pressure, etc.).
This revision is good enough to test with windrain.ino.
Updated scripts to use 9600 baud.
Made observations conditional on which node is reporting.
Added back in rain observations and gust usage in reporting.
Fixed for timezone madness.  I swear this used to work... I blame python.
Made temp reporting conditional on presence of temp data, improved console reporting.
