parser(text)

Given a feature file named drink.feature with the contents:

let feature = `
Feature: Can drink beer when thirsty
  As a drinker
  I want to take beer off the wall
  In order to satisfy my thirst

  Scenario: Can take a single beer
    Given 100 bottles of beer on the wall
    When a bottle is taken down
    Then there are 99 bottles of beer on the wall

  Scenario: Can take multiple beers
    Given 100 bottles of beer on the wall
    When 5 bottles are taken down
    Then there are 95 bottles of beer on the wall

  Scenario: Ghosts can drink
    Given 100 bottles of beer on the wall
    And there is nobody in the room
    When 5 bottles are taken down
    And they are floating in the air
    Then there are 95 bottles of beer on the wall
    And there are ghosts in the room
		`

When calling the parse function:

console.log(parse(feature));

Then the following JSON object is returned:

[
  {
    feature: 'Can drink beer when thirsty',
    perspective: 'drinker',
    desire: 'to take beer off the wall',
    reason: 'to satisfy my thirst',
    scenarios: [

        given: [

        ],
        when: [
          'a bottle is taken down'
        ],
        then: [
          'there are 99 bottles of beer on the wall'
        ]
      },
      {
        scenario: 'Can take multiple beers',
        given: [
          '100 bottles of beer on the wall'
        ],
        when: [
          '5 bottles are taken down'
        ],
        then: [

        ]
      },
      {
        scenario: 'Ghosts can drink',
        given: [
          '100 bottles of beer on the wall',

        ],
        when: [
