Proposal: Add a start button for the first card!
Inside serialize and serializeArray methods, loop to each elements who can be everything (e.g. input, textarea, select, ...).
Replacing input[disabled][data-serialize="1"] by *[disabled][data-serialize="1"]
Update README
Add showStart method. Hide back button in the first card. Replace next button by a start button on the first card
Update
Bug fixed merging data
Process start button on reset wizard
Add  tabindex="-1" to the modal otherwise escape action isn't working
Now serialize form elements not containing data-serialize="0"
Update README
Update, reset all fields when the modal is hidden. This update for resetting when the escape button is fired wasn't supported before!
