history.HisRecord: Strip Quantity objects back to base units.

Pandas probably won't like dealing with quantities, and while I can make
them convertable to floats, arithmetic operations raises the question of
what the result should be. (e.g. if you add a Quantity in metres to a
Quantity in inches, what happens?)
