  21  // IMPORTANT Info for devs who want to add to and/or use debug definitions!
  22  //
  23  // MAKING NEW DEBUG DEFS
  24  // The debug levels are Single Bit Binary Values. i.e, 1,2,4,8,16...
  25  // In the table below, if you want to define a new value, pick one of
  26  // the "FILLIN" items and give it the name and definition you need
  27  //
  28  // USING DEBUG DEFINITIONS
  29  // Since these are Bit Values, **never** test using < or > comparisons. Always
  30  // test using boolean operations, such as
  31  //    if (E107_DBG_PATH)
  32  //    if (E107_DBG_SQLQUERIES | E107_DBG_SQLDETAILS)
  33  // Since constants are defined for all possible bits, you should never need to use a number value like
  34  //    if (E107_DEBUG_LEVEL & 256)
  35  // And there's never a reason to use
  36  //    if (E107_DEBUG_LEVEL > 254)
