NOTE: Please read the following rubric before requesting a regrade. The general type of regrade we're expecting is 
if you feel you had a single bug that we didn't notice which caused you to fail SEVERAL of the tests.

ALIASING:
2 points for compiling  (part1.none)
2 points for append_alias and num_alias basically working. (part2.1)
1 point for delete_alias basically working. (part2.21)
1 point for delete_alias working when there are no aliases with that name. (part2.22)
2 points for saving aliases in the correct memory slot. (part2.2)
2 points for find_alias (part2.3)
2 points for print_alias (part2.4)
2 points for load_alias (part2.5)
1 point for save_alias (part2.6)


COMMANDS:
3 points for lookup_command working for simple replacement (part3.simple)
3 points for lookup_command working for argument correction (part4.args)
2 points for lookup_command use correct place for memory (part2.7)
     

CASTING:     
1 point get_spell (part2.8)
1 point get_spell_level   (part2.9)
1 point fireball, no target   (part2.10)
1 point fireball, at    (part2.13)
1 point fireball, can't find target   (part2.11)
2 points fireball, damage  (part2.12)
1 point heal, not self  (part2.14)
1 point heal, heal all of HP  (part2.15)
1 point heal, the amount of HP healed is capped (part2.16)
1 point cast, no spell  (part2.17)
1 point cast, invalid spell  (part2.18)
1 point cast, invalid level  (part2.19)
2 points cast, argument correction  (part2.20)
1 point cast working in game  (part5.cast)

* No points taken off for wrong output messages if the checks are correct. 

* For people with bugs in alias, return 1/2 credit for autograder points gained by fixing 
	a simple mistake  (e.g. not  calling delete_alias(name) in append_alias()) 

* Memory leaks
	>40 blocks lost (aka, don't free anything): -5 
	>20 blocks lost: -4
	>0 blocks lost: -3
	timeout/segfault: automatic -3

* Lower bounds on scores:
	10 - at least half implemented
	20 - hard to fix data structure / memory corruption / lookup_command bugs, but everything plausibly 
	     implemented
	30 - if all major bugs are fixable in a change or two

* Common Mistakes: leaking memory, pointer manipulation/list management in appending aliases, lookup_command, 
		  error checking in casting
