275 CTF Channel datasets

[Tom Holroyd]

By the way, VSM is now releasing version 5 of the CTF MEG
software.  The dataset format has changed slightly.  Code changes
will be required.  Datasets collected on CTF MEG systems with Acq
version 5, using the new ECC (electronics control console), are
going to be different.  We just got this upgrade; we haven't
gotten the new dataset libraries yet, though.  But the old
DataEditor just crashes when you try to read these new datasets.
