When a user selects a news item on newsPage.html,the news item should be displayed in the newsltem.html
page.
The app must periodically retrieve new news itemson the newsPage.html page.
The app must allow the user to save annotated news.

Email
When a user clicks the To button to email news items, only contacts that have email addresses shouldbe
displayed.
When multiple contacts are selected, the email addresses must be displayed in the To text box as a semi-colon-delimited string.

Titles for news items must not overflow into other elements on the page.
Authenticated users must be able to add handwrittennotes to the news items by using a stylus or the mouse.
The app must support saving annotations along with the news item. The app must cancel the navigation from
newsltem.html to newsPage.html if there are unsavedchanges in the annotations area.
Search capabilities
The app must retrieve a list of phrases from the news service and provide them as search suggestions to
users.
Authentication
Users connected to the corporate network must authenticate against an Active Directory server.
Users outside of the corporate network must authenticate by using forms-based authentication.
User credentials must not be transmitted in plaintext.
Application Structure
Relevant portions of the app files are shown below.(Line numbers in the code segments are included for
reference only and include a two-character prefix that denotes the specific file to which they belong.)
