Reuse of the ViewHolder class name

[kroikie]

Use CostomViewHolder instead of ViewHolder for custom View Holder.

I made this suggestion to Arthur in the office the other day. I was referencing snippets of the sample when writing something up and the reuse of the ViewHolder class name doubled the explanation length. Referencing CustomViewHolder as a class would have been much more concise and I believe it makes the snippets more readable when viewed in isolation. Just a suggestion.
