==Thermistor component==
A generic thermistor component that can be used to simulate and create code for any thermistor with a known temperature/resistance curve.  Thermistor is connected in a simple potential divider circuit - thermistor between ADC input and 0V, and a fixed resistor between ADC and the positive supply.  The component is also used with the EBM003 module, in which case the extra circuitry is already included.  Default calibration is for the EBM003 module.
