Allow customisation of each cell in a Section before its used 

this came out of my Evolve talk.

Allows a Section to customise its elements before they are used - so you can change the background of the element correctly without changing how the element works.

Another way could be to make the Section implement an interface like IElementResizing, not sure if an otherwise blank method call is quicker/better than a "if (x is ISectionCustomisation)" type call. Happy to rework if it is.

Should have submitted this a year ago. :(
