// The following macro and class allow for a very quick, runtime-settable loging function
// Essentially if the value passed into the macro as "TYPE" is true, it will then log the given text.
/* code snippet example below
 bool someLogType = true;
 LOG(someLogType) << "someLogType.Log this please!\n"; // the text will be logged
 */

#define LOG(TYPE) (TYPE) && logger::outstream
#define LLOG(TYPE) LOG(TYPE) << #TYPE << ": "
// The LLOG Macro will produce results like:
// LLOG(MyLogType) << "A fancy log\n";
// output = MyLogType: A fancy log

// This works because the boolean && operator stops at the first false value in the expression.
// So, if the value TYPE is false, no further evaluation will occur and the rest of the line will be ignored

// Here are some standard logs I've used
#define VERBOSE logger::verboseLog
#define NORMAL logger::normalLog
#define DEBUG logger::debugLog
#define CONFIGTEST logger::configFileTest
// add your own log types here and in the cpp file!

// To use, simply include the logger.h header file in your program, add the logger.cpp file to your target and use the code snippet:
/*
 NORMAL = true;
 VERBOSE = false;
 DEBUG = true;

 LOG(NORMAL) << "I'll print\n";
 LOG(VERBOSE) << "I won't\n";
 LOG(DEBUG) << "But I will!";
