Provide a sample for complex / hybrid widgets

In the context of consulting we started doing some code to demonstrate to a client :

• how to fetch data from a JSON service and display them in a suggest box
• how to make a custom widget that allows to link a widget and a sub layout
• how to configure all that from within Nuxeo Studio

This resulted in 3 modules :

• nuxeo-directory-connector
  • this module was cleaned up and extended for the occasion
• nuxeo-compoundform-sample
  • custom widget template + seam bean
  • showed a hot reload issue with Seam Bean and Nuxeo IDE when using a base class
• compound-form studio project

We now have all material to :

• make a good sample
• write some documentation

The goal is also to show that making custom widgets that mix JSF and JS is actually much more easy than what most people think.
