First draft of rule configuration

rule.yaml

{
  "event": {
    "type": "UserHasSignedUp"
  },
  "conditions": [{
    "type": "DateRange",
    "parameters": {
      "startDateAndTime": "01/12/2017",
      "endDateAndTime": "21/12/2017"
    }
  }],
  "actions": [{
    "type": "SendDiscoutCodeEmail",
    "parameters": {
      "email": "{event.parameters.email}"
    }
  }]
}

• A event must implement a given interface
• Each condition is a Validator that implements the ValidatorInterface
• A action must implement a action (command?) interface

This is translatable into a Object structure based upon the ruler/ruler package and possible to be compiled into a user interface.

The format above is considered the persisted data

@sorenmalling Nice one. Just two (more or less random comments):

1. JSON is probably fine as serialization format, but it should be validated somehow (e.g. you have a typo above that would only be detected during runtime otherwise - if at all)
2. Condition != Validation. I wouldn't mix up the two and introduce a new ConditionInterface instead
