- expr add string: don't call valueOf if the argument is already a
string
- inside String.java, if it called it's own function 'length()', NameNode
didn't generate code, fixed that in NameNode:checkType

- ClassInterNode better errors
- NameNode:checkStatic fix what happens when we encounter a primitive
type

- added fieldType to FieldNode
- added myType to NameNode
- fixed NameNode:checkStatic
- recursively calling disambigName exactly the same as how we do
checkType
- starting NameNode:checkType
- cleaned up Test.py commented code

Added code for Name disambiguation. Fixed CFG for field access. Moved test cases to the correct directory. Not tested yet
