title: Creating NSMatrix of NSImageCells
body: <p>I need to create an NSMatrix with NSImageCells bound to an array controller. So the content of the NSMatrix is bound to an NSArray (so there are as many NSImageCells in the matrix as there are objects in the array), then the image path of the NSImageCells are bound to a key called "iconPath" in the Array Controller.</p>
  
  <p>And then when an image cell is clicked in the matrix, I need it to perform an action. I know how to use bindings, and I have a concept like this working in an NSTableView, but I have never used NSMatrix before, so are there any good resources or sample code that would help me get started with this?</p>
  
  <p>Thanks</p>
