Add and Example Script

[andykemp]

I've added an example script which uses the framework to create a separate .txt file for each book in markdown format which includes all quotes, page numbers, notes and generates a kindle:// link to the highlight.

I use this to save to my dropbox folder and then display in Uylsses as a writing prompt.

Should say this is reliant on changes in my other PR.

I left some feedback on https://github.com/speric/kindle-highlights/pull/19, some of which I now realize I should have left here.

Either way, my general comments remain the same.

Thanks for these PRs. 👊
