/*
  Usage:

  1. implement this semantic that returns a promise that fires when the event happends and returns a context that will be send to the user
    [
      ({context, hierarchy, args}) => context.happening && context.marker == 'is' && args({ types: [<list of types>], properties: [<list of properties>]}),
      ({context}) => {
        context.event = Promise.resolve( { marker: 'event' } )
      }
    ],

  See time.js for example of use of args. args checks the list of properties for properties with the specified types. If all are found then a list of the properties ordered by the types if presented. For example,

    {
      marker: 'is'
      one: { marker: 'ampm' },
      two: { marker: 'time' },
    }

    args({ types: ['ampm', 'time'], properties: ['one', 'two']}) returns ['one', two']
    args({ types: ['time', 'ampm'], properties: ['one', 'two']}) returns ['two', one']
