    keyword=Swapped Blumi1 and Blumi2 cables

    Riad and I took an opprotunistic access to swap the signal cables between 
    blumi1 and blumi2 (blumi2 is quite odd, to say the least).
    
    Here's what we did while we were down there:
    
    0.   Noticed that the BNC->FatTwinAx adapter Box for blumi2 was in contact with 
    the lead shielding that it was sitting on top of.  Moved it on top of the 
    rubber padding (in an attempt to insulate it).
    
    1.   Checked the capacitors used on the grounding line at the BNC->Fat TwinAx 
    adapter boxes for blumi1 and blumi2.  Both caps were not continuous (good).
    
    2.   Swapped the signal cables, at the Adapter Boxes, between blumi1 and blumi2.
    
    We'll see if this has an impact on the strange signals we observe in blumi2.
    
    I've updated the database file templates to reflect this change.
