PythonASTAnalyzer(ast.NodeTransformer)

1. custom subclass of ast.NodeTransformer
2. visit : save variable names
3. used for understanding the overall structure of Algorithm code
4. since it is used for understanding overall structure of code, it doesn't track actual value on runtime
5. creates AST structure of tree and order and nodes in ast-graph.png.

ValueTracker(ast.NodeTransformer)

1. used for observing variables in runtime
2. visualizes each turns of loop through graphviz
3. show values of variables in runtime
4. results are saved in /graphs/${YYYYMMDD_TT_MM_SS}
