use luajit, ncurses(w) to create a command line ui
#!/home/dixyes/awsl/pl/luajit

First to say : ffi niubi!
This file is ncursesw command line ui written in lua, using luajit and some C things.
Note: pits here:
1. variables created by ffi.new("sometype") may be gced at anytime (maybe use ffi.typeof() to create type can resolve this.);
workaround: use ffi.C.malloc instead
2. struct index may be not reliable: for example a structure struct sStruct{u32 lFirst; u64 llSecond;}; when use instSStruct[0].llSecond, it will use area from llSecond's half to out of bound 4 bytes as llSecond.
