Similar to mine except that I implemented with all of the memory (data, 
instruction, input and output ports) with the Data.Map library.  One 
thing to care about is the heap memory profiling.  You'll need to make 
sure that Map.insert function do not pile up as thunk.  This is a 
typical memory leak profiling with most purely functional lazy data 
structures.  I only tried the first problem, and it was good enough 
performance.  But I don't have an idea how may timesteps it takes for 
the Operations Clear Sky.
