Errors ! Help needed. I think, problems due to hardcoded paths.

I cloned the repo and then created a virtual environment and installed requirements.txt.

Now I moved into examples directory and tried running fib.py . Got this error.

Traceback (most recent call last):

pydot.InvocationException: GraphViz's executables not found

I tried running

python examples/fib.py

I got this error:

Traceback (most recent call last):
  File "/home/aahnik/recursion-tree-plotter/examples/fib.py", line 4, in <module>
    from recursion_tree_plotter import plot_recursion_tree
ModuleNotFoundError: No module named 'recursion_tree_plotter'

I copied fib.py to the root directory of project and then ran python fib.py

Got this:

I think as Directory paths are hardcoded. So all issues are coming.

It would be great, if we packaged it and published to PyPI.
