select 'shortest' then will sort words from shortest to longest.
select 'longest' then will sort words from longest to shortest.
select 'a' then will sort alphabetical order.

HTML

• a select element with the name attribute "sort" to create a drop-down list.
• 6 option tags inside the select element define the available options in the drop-down list.

CSS

• styling to position the drop-down list correctly on the screen

Listeners

• a listener connected to the select, I'll try a "click" event first

Handlers

• one handler that sort the word list and re-render the list in the UI

Utils

• none.

Components

• none. I can reuse the component from add a word to render word list.

• this will be developed on the branch 4-feature-sort.
