[cal,errorRet] = SetSensorColorSpace(cal, T_sensor, S_sensor, [quiet])
Initialize the sensor color space for use in calibration. Requires
a calibration structure which contains the standard
fields. These are checked for and a message is printed if
they are not there.
Checks that wavelength sampling is consistent and splines
errorRet indicates status of the operation.
== 0: OK
== 1: Bad condition number on linear/device conversion matrix
quiet flag suppresses error messages, default 0.
