[ee122] persistent structs

[Daniel Killebrew]

Where the structure is allocated doesn't matter, as long as you are 
using memory during its lifetime (for example, not using a pointer to a 
structure that was allocated on the stack frame of a function that was 
called and returned.)

So to answer your question, no.(Do any of these structs have to be 
persistent (aka on the heap)?  )
