;AdcCal==========Starts a calibration conversion.
;C Function prototype: char AdcCal(char cType);
;Description of Function: Start a calibration by writing cType to ADCCON3.
;User interface: Set the bits in cType as desired.
;		See data sheet for meaning of individual bits.
;		Call AdcCal() to write cType to ADCCON3.
;		Activates gain callibration (GNCLD = 0).
;		Returns 1.
