Last refactor I'll do kinda like refactor # 6/7

I decomposed conditionals since some of them were needlessly nested which makes it harder to read for exampl

getFieldValue had like 4/5 nestings which is way too much

also did it on the other get methods I implemented and added one more test to make sure that after the decomposing of condtionals
code like this still worked

if(_exceptions.length == 0) {
   printIndented(depth, "  Exceptions-> NONE");
   return;
}

Done Assignment!
