cleaning up the sensor designs because they where a mess and i'm going to make two different ones one that is a single board and one that is a carrier for the AMS dual version

keeping the original single board design and adding a second one with a new base board that will use the same dual sensor board as the AMS

1.02 update removed the unity gain output op amp and Gain trim pot and replaced it witha  0.1% 665 ohm resistor for the instrumentation amp. simplified the voltage reference and 5v circuits. Added an output Pot to be able to to limit it to 3.3v volts. Added an optional arduino nano v3 and rs232 output. along with a NTC 10k Thermistor for temp compensation calcs.

making some corrections and updates.

added what the basic what the hell i'm doing.
