Book club roulette troch FufuDev

How to run/test the app:

Preparing the spread sheet:
1. Enter to a Google spread sheet where you have reading permisions.
2. Add these required headers (Be aware of using the caps and spaces im using): "Nombre", "Autor", "Propuesto por", "Estatus".
3. Add some lines down those headers, add some books you know.
4. Take special atention to the "Estatus", since we use this value to filter the results later on.

Staring the app:
1. Open the page action that is shown in the address bar of your browser.
2. Wait untill the loading message disappears.
3. In the drop down menu / select input, is shown, select some term, to filter the data that is in your spread sheet. Then click the button bellow that.
4. Now you are in the preview screen, click the button bellow the list of books (now filtered), again to be sent to the next screen. (In this preview screen, you can also delete books from the app [it will not affect the actual spread sheet]).
5. In the roulette screen, you can add a number of attems (if more than 1, the roulete process will be repeated, discarting the chosen book). Click the button bellow to start the roulette.
6. After the roulette finishs (it takes between 15-30 seconds randomly). It will take you to the results screen.
7. If you entered more than 1 attemps, it will let you start again.

Notes:
The app is in Spanish, since it will be used only in that language.
