Subject: [PATCH] Add sample for Display Html Helper.

Showcased a lot of the core pieces of Display in the sample.  Some pieces are still missing such as DataType handling.  The infrastructure is there to handle it in the TemplateRenderer but the model metadata providers do not construct the metadata with the data types.
