Debug level

There are 5 debug levels can be set: debug, info,warn,error,fatal and none.

the debug level grades are: debug<info<warn<error<fatal<none, for example:
if the preprocessor's debug level is set as 'warn', the code:
//#debug debug
System.out.println("debug");
will not print the "debug" in the console. but the code:
//#debug error
System.out.println("error");
will print "error" in the console.
the preprocessor's debug level can be specified in project scope.
