Rely on two types with if statements
* I worry about the simple constructors here though. I believe that causes things to be instantiated on the stack which is then blown away. That would mean that I would need to rely on the heap with the new keyword, but if I do that I will need to deallocate later. * Digging into DS3232RTC, it looks like it has no deallocator, and I kind of suspect the same for Rtc_Pcf8563. Either way, we will want to ensure that we can delete those classes where we need to. I would hate to introduce a memory leak somewhere on something so smallpull/120/head
