As an administrator I want to be able to add/edit/remove available programs

In the admins page, administrators should be able to add programs, alter programs and remove programs. All the programs should be listed in a table, each with a view info, edit and remove button. There should be an add new program button above the table and when clicked it should open a dialog to insert information including the name start/end date, a general description and the closing application date. When the view information button is clicked it should open the existing program information for view, the information can also be edited here. When delete is clicked a confirmation should pop up to confirm deletion.
