'rope function called outside of dispatch function or inside coroutine' when using rope:parallel about corope

[bakpakin]

I have taken a look at your code and added an example in the examples folder. There was a slight problem with the parallel function which I have fixed.

In parallel, each of the functions that runs gets its own new rope, which use should use to control the timing.

bundle(function(rope)
    rope:parallel(
        function(ropea)
            print "First"
            -- Don't do rope:wait(0.5)
            ropea:wait(0.5)
        end,
        function(ropeb)
            print "Second"
            -- Don't do rope:wait(1.5)
            ropeb:wait(1.5)
        end
    )
    print "Last"
end)

While Lua coroutines are powerful, there are some limitations in jumping between them. One can only manipulate a rope within a single coroutine (there is a 1 to 1 correspondence with coroutines and ropes). When trying to wait on the original rope inside the parallel function, you are in a different coroutine (the one corresponds to ropea or ropeb). Fortunately, we can create as many ropes as we want and wait on those ropes.
