  A setuptools based setup module to install willowtree on your personal
  computer.
  
  How does it work?
  -------------------------------------------------------------------------------
  On Terminal (macOS) or Command Prompt (Windows), navigate through folder
  'willow-tree', then run ($ is the Terminal prompt):
  
  $ python3 setup.py install
  
  This command will generate three folders in the current directory:
  
  build
  dist
  willowtree.egg-info
  
  and one .egg file in the main package folder, for example, if third-party
  extension Anaconda is installed, in 'anaconda/lib/python3.X/site-packages':
  
  willowtree-X.X-py3.X.egg
  
  where X.X refers to the most recent installed version of 'willowtree', e.g.
  0.9, and py3.X to the latest installed Python version, e.g. 3.6.
  
  It is now possible to import willowtree in a Python environment.
