Add example scripts link to documentation

[Chris7]

Add a link to this page: https://github.com/wooey/Wooey/tree/master/wooey/tests/scripts

To give users some example scripts to start off with.

Hi, I ran into errors when trying to run the "without_args" sample script. It just waits eternally after you click Submit and the console where I have the server running returns:

Internal Server Error: /scripts/no-arguments/ Traceback (most recent call last): File "C:\{path}Programs\Python\Python35-32\lib\site-packages\django\utils\datastructures.py", line 83, in __getitem__ list_ = super(MultiValueDict, self).__getitem__(key) KeyError: 'wooey_type'

This also happened with another script I was trying to run without arguments, so it is reproducible.

Hey @arolling

I have a few questions for this:

Is {path} really in your traceback? Also, by wait -- do you mean the webpage hangs or doesn't update? Are there errors in the developer's console? And did you start the project with wooify?

[arolling]

Thanks @Chris7 for the quick response!

Yes, we started the project with wooify. I'm not sure what you mean by developer's console - the browser just stays on the webpage where you click "Submit" and that message (I replaced the file structure of my PC with {path} because i didn't think it was relevant) appears in the Command Prompt window where I am running the Django server (python manage.py runserver). The admin console for Wooey does not show it in the list of jobs. Here is the full traceback:

Internal Server Error: /scripts/no-arguments/

KeyError: 'wooey_type'

During handling of the above exception, another exception occurred:

As mentioned in my other issue, we are running with Wooey_Celery set to False, but other scripts with arguments do run successfully (like "choices").
