Saving file directory is hard-coded by the relative path in the code

[Shine226]

We need to find a better way for the saving path. JS doesn't provide a way to browser a folder dialog.

Current research:

• https://flask.palletsprojects.com/en/1.1.x/config/
• http://peak.telecommunity.com/DevCenter/setuptools#non-package-data-files

Possible temporary soln

put only config_example under version control and the config file will have the location on that local system where the person wants things saved for now we can require the person to manually edit that file and in the futur we can figure out how to do it automatically

when this is solved docs/source/wiggum_app.rst needs to also be updated to reflect this changed

[brownsarahm]

If we get this one solved, we can submit Wiggum to pipy, but if this is not solved, we can't because Wiggum can only currently work if run from the same directory as the data, which is complicated.

We might be able to come up with another workaround set of instructions for how to launch the app so that it can work without being launched in the code directory, but one of these needs to happen before submitting it to pipy makes sense.

these can help for data we provide, but not for use-provided data

This issue captures multiple related problems:

• [x] cannot open data from other places
• [ ] wiggum needs to be launched from the directory where you want to save
• [ ] need to be able to access default data from installed copy

Tried flask.send_file https://community.plotly.com/t/allowing-users-to-download-csv-on-click/5550, but the function doesn't send file to anyplace.

I added code under 'save' action: send_file('/Users/chenguangxu/Documents/GitHub/detect_simpsons_paradox_dev/data/genderpaygap/df.csv' , as_attachment=True)

Since os.path.join(directory,data_csv) doesn't give me a correct path, I used a hard-coded file path instead.
