Testing for MPL115A1 barometric pressure sensor code.
Currently grabs coefficients correctly.
Fix to computation of c12 coefficient.
New MPL115A1 library based on code found online (details in comments).
Unable to get my floating-point based code working - sent email
to freescale for clarification on computing b1 constant - the
datasheet method doesn't match the datasheet example, so both are
suspect.
