/// of the accesses involve references to these static globals that get set up. This won't be the fastest set of pin operations, but it
/// will provide pin level access on pretty much all arduino environments. In addition, it includes some methods to help optimize access in
/// various ways. Namely, the versions of hi, lo, and fastset that take the port register as a passed in register variable (saving a global
/// dereference), since these functions are aggressively inlined, that can help collapse out a lot of extraneous memory loads/dereferences.
///
/// In addition, if, while writing a bunch of data to a pin, you know no other pins will be getting written to, you can get/cache a value of
/// the pin's port register and use that to do a full set to the register. This results in one being able to simply do a store to the register,
/// vs. the load, and/or, and store that would be done normally.
///
/// There are platform specific instantiations of this class that provide direct i/o register access to pins for much higher speed pin twiddling.
///
/// Note that these classes are all static functions. So the proper usage is Pin<13>::hi(); or such. Instantiating objects is not recommended,
