title: Eclipse plugin: New file wizard extending INewWizard, how to get selected project to create in it
body: <p>I'm currently writing an eclipse plugin, and in it, I have a new project creation and a new file creation wizard.</p>
  
  <p>In the new project wizard, I create it, so I have no problem getting it and creating new files in it. (like creating the Main class for your project)</p>
  
  <p>But when I'm in my New file wizard, I have literally no idea how to select the right project, and I would like some help please. 
  Since it is a wizard, I would like to avoid needing an opened editor, and since it's a new wizard, it doesn't have a handler so I can't get it from there...</p>
  
  <p>Thank you in advance,
  Cordially,</p>
