While the event flags in SleepStyle data show four different types of apneas,
Fisher & Paykel software reports only two types: Hypopneas and Apnea. OCAR
how combines those four types to report the same way as F&P does.
We don't know why F&P consolidates these different event types -- perhaps
they are "dumbing-down" detail to make it easier for users, or perhaps
they know that the identifcation of CA, OA, UA, and H is not reliable.
We can easily restore more details to the event identification.
This is the first test version of the F&P SleepStyle loader
Additional refinements are yet to be made. Events and timestamps
need to be confirmed, but overall the loader appears to be working.
