Update showcase

[jouni]

• Move GWT integration “tab” to last in the sidebar
• Add “Vaadin Grid” tab after Iron elements
  • Start with the "REST API data source" sample
  • Add frozen columns
  • Add column hiding and reordering
  • Sorting

@jounik finally I did the long way of making vaadin-grid work with the gwt-api-generator.

In this way the demo code looks simpler since the WC api is less complex than using vaadin-widgets.jar and the demo was easier to write because I reused some material from vaadin-grid examples.

The demo shows more features than the set defined in this card, so we have:

• ajax
• frozen colums
• hiding (no reording)
• sorting
• cell generators
• class generators
• resizing
• filtering using paper-input
• row details

I think it's more logic to use the grid as a web component in the showcase, because the audience expects that.

Oh, wow! That sounds great! I wasn’t expecting this to work so soon.

This is probably pending some patches in vaadin-grid, right?

Yes we need: https://github.com/vaadin/vaadin-grid/pull/239 https://github.com/vaadin/vaadin-elements/pull/21
