Missing rules for grammar (from part 1), also kep in mind for derv-ass.

Problem analysis got point reduction for soundig too much like the design.
It should only be the problem in general, nothing to do with code implementation

Missing valrind completely, lol, it was a rtf file, when you tried to latex it as a txt.file
it got shitfucked completely, It wasnt even Lauris valgrind anymore, our report just contained
a bunch of latex-errors as a valgrind xD

Minus for using globals, also minus for using doubles(and globals) as if-conditions

That's it :)
