finish the Austocomplete.js script, first review my current use in EditorContent.js, this is auto complete is specifically for the headings and speaker types, for example INTERIOR | ROOM AT NIGHT or DAVE are values we are going to use over and over. The user can press tab or enter to accept autocomplete or they can keep typing to type over it, therefore we will need to use the event to show and manipulate the auto complete text. to start just use INTERIOR, EXTERIOR in one data object and TOM in another as the only value we can match on, also remember we must be able to know which line type we are typing into and check different data objects.

Do you understand my requirements?
