When DEBUGLEVEL is not defined/// these macro's evaluate to nothing.//////If DEBUGLEVEL is set to 1, Level1 debug info is printed. If DEBUGLEVEL is set to 2, all Level2 and lower are printed. etc.//////Which level you use for what is totally your choice, but I try to use this:///1. Current debugging problems ONLY///2. Single run messages (initialization etc.)///3. General messages///4. Messages inside loops and large messages (common)///5. Messages inside multiple loops or very large//////To set the debuglevel of a class, place \#define DEBUGLEVEL in the internal header file (in contrast to the header). This will keep multiple defenitions from occuring when compiling.//////The output generated is: "[Filename]:[Line number]: [information]\n"//////The extraction operator is used for creating the debug line, so info can contain more then multiple elements devided/// by extraction operators.///\section examples Examples///\code/// _debugLevel2("Starting algorithm with:" << "something.");/// _debugLevel3("And thinking about running it" << i << " times.");///\endcode///NEW: FLUSHING HAS BEEN DISABLED, ENABLE FOR SEGFAULT DEBUGGING///NEW: NO_DEBUG WILL DISABLE ALL DEBUG STATEMENTS, DEFINE IT WITH THE g++ ARGUMENTS//No include guards, to keep the defenitions as much up to date as possible, due to the dependencie on DEBUGLEVEL.#ifdef BATS_NO_DEBUG  #ifdef DEBUGLEVEL	  #undef DEBUGLEVEL  #endif#define DEBUGLEVEL 0#endif#ifdef _debugLevel1#undef _debugLevel1#endif#ifdef _debugLevel2#undef _debugLevel2#endif#ifdef _debugLevel3#undef _debugLevel3#endif#ifdef _debugLevel4#undef _debugLevel4#endif//Change this from "\n" to std::endl to disable/enable flushing#define __DEBUG_LINE_ENDING_STATEMENT__ std::endl#include <ctime>#include "timeval.hh"#if DEBUGLEVEL > 0#include <iostream>#define _debugLevel1(info) std::cerr << mvds::TimeVal::getTimeOfDay() << " D1:" << __FILE__ << ":" << __LINE__ << ": " << info << __DEBUG_LINE_ENDING_STATEMENT__#else	///\brief Output info when DEBUGLEVEL is 1 or more	#define _debugLevel1(info)#endif#if DEBUGLEVEL > 1#define _debugLevel2(info) std::cerr << mvds::TimeVal::getTimeOfDay() << " D2:" << __FILE__ << ":" << __LINE__ << ": " << info << __DEBUG_LINE_ENDING_STATEMENT__#else	///\brief Output info when DEBUGLEVEL is 2 or more	#define _debugLevel2(info)#endif#if DEBUGLEVEL > 2#define _debugLevel3(info) std::cerr << mvds::TimeVal::getTimeOfDay() << " D3:" << __FILE__ << ":" << __LINE__ << ": " << info << __DEBUG_LINE_ENDING_STATEMENT__#else	///\brief Output info when DEBUGLEVEL is 3 or more	#define _debugLevel3(info)#endif#if DEBUGLEVEL > 3#define _debugLevel4(info) std::cerr << mvds::TimeVal::getTimeOfDay() << " D4:" << __FILE__ << ":" << __LINE__ << ": " << info << __DEBUG_LINE_ENDING_STATEMENT__#else	///\brief Output info when DEBUGLEVEL is 4 or more	#define _debugLevel4(info)#endif
