Create a workflow package tutorial

  The following is a tutorial that shows how to create a workflow package deployable in eXo
  and that models a sample procedure to approve holidays. This workflow is a basic example
  and covers fundamental aspects that can be reused while developing your own business processes
  in eXo.
  
  The tutorial describes all the steps to reproduce and compile the example. The final source tree
  to be obtained is available at {{{holiday-standalone.zip}here}}.
  
  Note: this workflow's name is "holiday business process standalone", so you could 
  load it even if you already have the "holiday" Business Process bundled by default in eXo.
