Allow for recursive IronBoxes #4
Description
An IronBox in an IronBox... I am not sure why this feature is important but it is pretty cool anyway. :)
This will involve changing the C code and the way it registers hooks. This is because LuaJIT and Lua5.1 only support one c hook for every Lua instance. (Coroutines and IronBoxes are not actually separate Lua instances.)
This the sub IronBoxes will have to have their hooks registered in a way such that sub-boxes yield when the parent box does too so that execution limits are not evaded.
