Task Resolution Screen

See the attached screenshots.

• As a user being assigned a task,from the workflow dashboard, I can click on a "Process task" button. Instead of bringing me to the Document view, it displays, within the left "Workflow" tab, a task resolution view. This task resolution view is based on a grid layout and displays:

• • The list of documents that are bound to the workflow related to the task. I must be able to download the file or preview it, or browse the document.
  • The task informations
  • The task form and user actions

From that view, I can also:

• • see the current workflow graph
  • re-assign
  • delegate
  • go back to the previous screen

• From the document view, when I am assigned a task, I can see it from the document (I just see a content view with the same kind of information than on the tasks dashboard. I can "process" a task from there. In that case, it changes the central view, but I stay on the document view, with tree on the left (same like the export view)

• As a user having a task assigned to me on the same workflow instance right after I started the workflow or resumed a task, the system directly redirect me to the next task resolution screen.

There is a default task-resolution view, and it is possible to override it from Studio for a specific node of the workflow.
From Studio, on the configuration screen of a node, on the general tab, I can choose a Tab feature instance that will be used for configuring my screen.
If I want to display the document list, I will use the content view widget, with a specific binding for the data list to display (We may add a specific widget in the future for having the binding automated, but that's not necessary now).
I have a task widget that I can use for displaying the task info, and a "task form" widget for the data.

In the future (not on the first shot), I'll also want to be able to leverage the following information for designing my view:

• Document[0] bound to the route and its metadata (an easy way to provide a view layout when I know that my workflow is with one document only, instead of doing a listing layout with one row)
• TaskInfo : useful to have access to it especially when on a multi-task node (but let's do it later with more spec)
