// These are some macros to quickly turn on and turn off stack trace debugging in your program 
// to show the file, function, and line number the error happened at.
// To turn stack trace on, uncomment the following line. To turn stack trace off, comment the following line:
// Turning on stack trace causes larger and slightly slower executable code.
// I tend to leave it on, even in production because errors happen in production and it's nice to know where.

// Use DEBUG_FUNCTION at the start of every function.
// Use DEBUG_LINE several times during the function before and after critical pieces of code that might crash.

// Debug debug(__FILE__,__func__,__LINE__);
