- fix for Tests/A3/J1_supermethod_override11/

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

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

- if class extends no other class and implements no other interface, it
should inherit each method from java.lang.Object
- switched up a lot of " to be ', for my ocd lol
- removed contains attribute in ClassInterNode

- add fields to contain set
- added inherit set
- quick fix for final method getClass in java.lang.Object that was
creating errors

- removed getContains function from individual class and interface nodes
- now getContains is only in ClassInterNode
- added a new helper function to catch any errors when trying to replace
a method

- class/interface set canonName in constructing of node
- java.lang.Object super set = []

- Test.py stop printing stars so much
- ClassInterNode - create common fields in constructor
- create super & contain set for Class & Interface

- added package name to hierarchy
- made sure hierarchy was appended correctly in recursion
- fixed Test.py to test single files, and to produce total result

- fixed getParseTreeNodes
- fixed getting name for TypeNode

- some more class stuff

- added CompEnv, which is a special enviornment for CompNode where it
also stores the imported stuff and the package name, so you can search
the globalEnv with those as well
- added type linking to ClassNode, where it checks the extends and
implements classes/interfaces and makes sure that they are real, and
stores them as the nodes in ClassNode
