Unfortunately my post does not answer your question. I googled the concept and collated some links however they are all theory based from university studies over the past 10 years. Chances are you already know the theories. I am sorry if my links are irrelevant to your question which is asking for an appropriate coding approach.

A coder might happen by sooner or later who knows the correct approach you can use.


Several links are local google url's so I am not sure will be working. Majority are pdf's.
