CLI Meter
====================================================================
Takes a reading of the light using the meter attached via to the
intended Raspberry PI. The reading is the sent to a server where the
reading is stored. The intended use for this script is to be run via
the command-line without the need for a G.U.I. This should be the
version used when the "Return to Ritherdon" project is live.
