Use the vignette to explore how to do an API call and visualise the results

[stephlocke]

We should show people in the vignette how to do an API call to get data, what sort of things they may need in order to do so, and how to interpret the resulting chart.

• API docs: https://www.ibm.com/watson/developercloud/personality-insights/api/v3/

Things to remember

• Any extra libraries like httr mentioned in a vignette need to be added to the DESCRIPTION in the Suggests section
