LearningEvaluation usage of setArgs ambiguous about marioai HOT 5 CLOSED

Yes, thanks for spotting this question up -- it also requires some 
clarification. In the beginning it was only the sequential approach elaborated, 
i.e. it is obvious here what's happening:
CmdLineOptions c = new CmdLineOptions(); //all documented defatuls
c.setEnemies("g:10"); // 10 goombas
c.setInvulnerable(true); // defaults, but 10 goombas and Mario is invulnerable 
to creatures.

WOuld you say that c.setArgs("...") should be invariant w.r.t. place it appears 
and c.setEnemies("g:10") should drop 

In this case the cumulative changes are a bit harder to "collect". Now, the 
class does it for you, and by keeping track what's there, one can tweak the 
levels in a desired way. Otherwise in GamePlay it will be necessary to spot 
each additional parameter explicitly as CmdLineOptions class will not store all 
the changes step-by-step. Yet the initial idea of using hash map was also this 
one: to keep track of previous changes.

I came up with this idea: CmdLineOptions.reset() method, that drops all options 
to defaults and is called whenever required. This will keep current behaviour 
and would allow to have invariants of set of options that uniquely define the 
level.

I can definitely see the convenience of being able to build up options, and 
like your solution of adding a reset().  This way if someone was worried about 
it and wanted to set everything explicitly they could call reset() and not have 
to worry.

Thanks.
