* Adding a cylinder pressure sample field is not quite as trivial as it

* perhaps should be.
|
|
*
|
|
* We try to keep the same sensor index for the same sensor, so that even
|
|
* if the dive computer doesn't give pressure information for every sample,
|
|
* we don't move pressure information around between the different sensor
|
|
* indices.
|
|
*
|
|
* The "prepare_sample()" function will always copy the sensor indices
|
|
* from the previous sample, so the indices are pre-populated (but the
|
|
* pressures obviously are not)
