// NOTES 1, 2, 3
// because "integers" is declared as uint8[10], getArray() must return type uint8[10].
// setArray(...) does not require uint8[10] input, but you'd then have to check to make sure the two arrays were of the same type and length.

// If "integers" were declared as uint8[] (dynamic length), then I'd have used getArray() and setArray() with uint8[] instead. 
// setArray would then obviously require a length check for compatibility.
