Version Awareness

[jayqi]

• Version awareness for post-save hook installation. Resolves Check for existing config and don't process if not new #16
  • Add versioneer for version management
  • Add a --version flag to CLI. I copied this example from the Typer docs.
  • Post-Save Hook installation is version-aware:
    • Version is included in comment string
    • Detects existing nbautoexport post-save hook
    • Replaces existing block if current version is higher (including if there is no version)
• Create all directories necessary for Jupyter config file if they don't already exist. Seems reasonable given that we create a blank config file if the directory exists but the file doesn't. Resolves How to handle missing Jupyter config directory #19.
• Narrowed coverage to only report on source files in nbautoexport/, excluding _version.py from versioneer. This looks like:

Name                           Stmts   Miss  Cover
--------------------------------------------------
nbautoexport/__init__.py           5      0   100%
nbautoexport/nbautoexport.py     136     46    66%
--------------------------------------------------
TOTAL                            141     46    67%

This is awesome!

Now that this method is getting more complicated, let's see if there's a good way to store this block as Python code so it gets highlighting in source control and could be easier to test directly if we need to eventually. I think that we could either define the function and use inspect.getsource to get this code after the function is imported, or maybe just have it in a .py that we read instead of importing.
