SelectList with a null selection
I have a bunch of drop down lists in my view, such as this one:

    @Html.DropDownListFor(model => model.Process, Model.ProcessList)

They all take in a `SelectList` based on data from a database table like this:

    ProcessList = new SelectList(_db.Processes, "ID", "Name");

where `_db.Processes` returns a `ObjectSet<Process>`.

The issue I have is that sometimes the property that is set by the drop down list can be no selection, i.e. `null`.  How can I add a `null` selection to the `SelectList`>
