[Bug][Installation] ModuleNotFoundError: contextvars

[rajat404]

OS: MacOS Catalina 10.15 Beta (19A536g)
Python Version: Python 3.6.5
I installed diagrams in a new virtual environment, using pip

While it installed the package successfully, when I tried to run the example mentioned in Quickstart guide, I got ModuleNotFoundError: No module named 'contextvars' error.

I believe the lib contextvcars needs to be specified in the setup file

Same here:

$ python --version
Python 3.6.9
$ pip freeze | grep -i diag
diagrams==0.2.3
$python diagram.py 
Traceback (most recent call last):
  File "diagram.py", line 2, in <module>
    from diagrams import Diagram
  File "/home/aaron/.virtualenvs/diagrams/lib/python3.6/site-packages/diagrams/__init__.py", line 1, in <module>
    import contextvars
ModuleNotFoundError: No module named 'contextvars'

It is version issue for a library was added since Python 3.7. #13 can resolve this issue.

Please check with this version.
