/** TMP007 Temperature methods.

 * Example:
 * @code
 * #include "mbed.h"
 * #include "TMP007.h"
 
 * #define Address 0x40 // depending on pin ADR0 and ADR1 it can be either 0x40, 0x41, 0x44 or 0x45
 *
 * TMP007 sensor(p9, p10, Address); 
 *
 * int main()

 * while(1) {
 *   printf("TTemperature: %f F \r \n", sensor.readObjTempF(Address));
 *   wait(0.5);
