Add "truth-machine" example

[CristianCantoro]

The "truth-machine" is defined on the Esolangs wiki:

    Ask for input.
    If the input is 0:
        Output 0.
        Terminate program.
    Whereas if the input is 1:
        Repeat infinitely:
            Output 1.

I have added the example to the Esolangs wiki.
