Adding sentiment analysis - Indico and hopefully support for other RESTful APIs

[djplaner]

Trying to explore if I can quickly add support for sentiment analysis.

Plan is to allow support for any RESTFUL api - e.g. Indico will be the test case. Indications are that there are numerous other players - https://www.quora.com/Where-can-I-find-an-online-API-for-sentiment-analysis

Indico's API (https://indico.io/docs?api-keys#sentiment)

curl 'http://apiv2.indico.io/sentiment?key=__key__' --data '{"data":"I love writing code!"}' OR sentimenthq

The elements here are

• URL for the API call
• key parameter for the key
• data as a json data

Would need to include

• option on configure screen to turn on sentiment analysis and add in the required data
• also some way to test it
• How would I handle errors - is there a common method for error response to RESTFUL?
• When posts are mirrored, a call would be required - or does this become a separate cron job
• need to update database to specify sentiment analysis (-1 as not calculated)
• need to update displays (students and markers) to show sentiment
