Thanks.  I may take you up on that if I can't get it to work.  I've done 
enough work that I want to try it myself first.

I get my sensor tomorrow, but I've been learning and playing and writing 
with Python today.  I wrote and tested the calibration code, using the 
sample data on the data sheet, and I get the right answers!  That's a lot 
of calculation, and it was great of them to provide test data and 
intermediate answers so I could make sure my code was working.  

I want to use the SPI interface, and everybody else is using i2c,  I am 
also going to try running it in Normal rather than Forced mode, since that 
allows the filter to work better and still uses power in the microamps.
