Added context menu to xml resource file.  Next step is to inflate the menu when a long press is encountered over a task item
Have hovering context menu implemented.  Going to implement the action-style context menu to see how that looks, too.
Added onContextMenuItemSelected method to respond to context menu clicks
Moved Gesture Listener to Activity from Adapter
Swipe to delete and context menu are working.  Task title must be long pressed for context menu to come up.  Wanting to make it work with any part of the list view.
Improved longpress with swipe.  Everything works well together now.
