// The match functions were (apparently) originally MACROs to improve code speed
//   (although this would have bloated the code) hence the names being CAPS
// A later release implemented debug output and so they needed to be converted
//   to functions.
// I tried to implement a dual-compile mode (DEBUG/non-DEBUG) but for some
//   reason, no matter what I did I could not get them to function as macros again.
// I have found a *lot* of bugs in the Arduino compiler over the last few weeks,
//   and I am currently assuming that one of these bugs is my problem.
// I may revisit this code at a later date and look at the assembler produced
//   in a hope of finding out what is going on, but for now they will remain as
//   functions even in non-DEBUG mode
