The idea behind the example*
This example shows how to use react context api in our app.
It provides an example of using pages/_app.js to include include the context api provider and then shows how both the pages/index.js and pages/about.js can both share the same data using the context api consumer.
The pages/index.js shows how to, from the home page, increment and decrement the context data by 1 (a hard code value in the context provider itself).
The pages/about.js shows how to, from the about page, how to pass an increment value from the about page into the context provider itself.
*Based on WesBos example.
