Adding delete option

[Applitom]

Hi,
I am using CZPicker, it is really great component for my App.
I was needed to add an option to delete row from the list so i've added it.
It would be great if you will add it to the main branch so everybody will be able to use this option :)

Thanks!

Hi @Applitom , thanks for your pull request.

Everything is working well in the demo.

However I wonder in what circumstances would you want to delete an item from a picker?

In my Remote control app the user have the option to save and load playlists.
I'm using CZPicker to show to the user his Saved Playlists, and i want to have the option to delete Saved playlist if the user want to.

Can you give a animation after delete the row and then dismiss the picker? I think currently it was dismissed to quickly.
