restructuring - reorganized implementation for combination of comp with raw/timeloc/freq structure. There is now explicit handling of raw+comp, timelock+comp and freq+comp. In case datatype=comp, the timeseries fields are being removed by ft_checkdata. See http://bugzilla.fcdonders.nl/show_bug.cgi?id=1887
