void Fits::InitDataColumns	(	const vector< Description > &	desc,
		const vector< string > &	dataFormat,
		MessageImp *	out
	)

Adds columns specific to the service being logged.

This gives the file writter access to the DIM data

Parameters

desc	a vector containing the description of all the columns to log
dataFormat	a vector containing the FITS data format of all the columsn to log
dataPointer	the memory location where the DIM data starts
numDataBytes	the number of bytes taken by the DIM data.
out	Message object to use for propagating messages
