Behaviour

• The component does very little by itself. You provide it the input with props, and it renders it. To make any changes (like change active item, scroll items), you need to change props that you pass to it

  Ideally, you keep state in a (redux) store, and pass that state as props to this component. The callbacks are used to manipulate the store which shall eventually change the props passed, and render the component.

• The component will show scroll buttons (two buttons; one in front of the carousel and one at the end) if number of items in the carousel exceed the total number of items that can be displayed without overflowing the contents.

• The total number of items that can be displayed in the carousel is determined using the width of the component container, the itemWidth property value and itemMargin property value.

• The carousel shrinks if the container width can't be filled with items.

• onItemActivate will be given the key of the item that is clicked by the user.

• onItemScroll gets called when user clicks on next/ previous scroll button. It gives index of the new firstVisibleIndex item.
