Started find_item, so far have succesfully accessed the global items list head item
Finished find_item function/comments, need to add a general comment for each function describing params/return values
Finished find_patron, removed a redundant null check in find_item
Finished new_patron function
-Need to find out still if I just need to copy the arg name* into the struct or if I actually need to
allocate space and then strcpy it
Cleaned up new_patron was doing it correctly after all
Finished up new_item function, simplified new_patron by having the patron* start/end in %eax
