Hello world

to start a quick hello world:

// include ZFCore.h for core function of ZFFramework
// you may need to setup your project's include path first
#include "ZFCore.h"
 
// declare app's main entry
ZFMAIN_ENTRY() {
    // well, hello world to ZFFramework
    ZFLog() << "hello world";
 
    // use ZFLog or zfstr and `%s` to print "anything"
    ZFLog("hello %s %s", "world", 2);
    ZFLog(zfstr("hello %s %.2s", "world", 3.1));
}

ZFFramework would be started from ZFMAIN_ENTRY, you may write any C++ compatible code here
in this example, we just output "hello world" to ZFLog, which would output to a proper console by default
