TkSocket_00 - "DNS Lookup" with User Interface

"TkSocket_00" represents the graphical counterpart of the "Socket_00" example and also performs a simple "DNS Lookup". Main purpose of this program (as well as of the other TkSocket examples) is to test whether LuaSocket functions and Tk may be used together.

While "TkSocket_00" appears to be much more "costly" than its text-only predecessor, the source code still does not need any special explanation.

"TkSocket_00" should be invoked without any command line arguments 

  lua TkSocket_00.lua

and presents itself on the screen as follows:
