Example: Customizing SlickGrid

[rufuspollock]

Show how we can customize SlickGrid grid "normally" - i.e. you can get access to underlying grid and tweak it as you want.

Suggest we demonstrate using this example: https://github.com/mleibman/SlickGrid/blob/gh-pages/examples/example-plugin-headermenu.html

Idea here is: we don't want to mimic all that slickgrid can do through recline interface - just let people do it directly themselves ...

@mattfullerton would you be up for having a go at this - given what you seem to be working on ;-)

Maybe - but first i need a working setup with SlickGrid (#432). What I am working on... I was asked to add a table to okfde.github.io/ebdmap - easy I thought... I had no idea what I was getting myself into, but about time I was forced to get familiar with recline

I've booted a page for this at docs/tutorial-grids.markdown. A basic tutorial and demo for getting up and running is under the views tutorial.
