Merging resumes fails (Cannot read property 'markdownify' of undefined)

[RichyHBM]

When merging 2 cvs, 1 with full content and 1 with partial, HackMyResume fails to build the html and pdf versions.

For example: cv1.json

{
  "name": "Jane Q. Fullstacker",
  "meta": {
    "format": "FRESH@0.1.0",
    "version": "0.1.0"
  },

    "brief": "**Full-stack software developer with 6+ years industry experience** specializing in scalable cloud architectures for this, that, and the other. A native of southern CA, Jane enjoys hiking, mystery novels, and the company of Rufus, her two-year-old beagle.",

    "quote": "Be the change you want to see in the world."
  },
  "social": [

      {

        "position": "IT Administrator",
        "summary": "Junior programmer with heavy code responsibilities. Promoted to intermediate role after 6 months.",

        "highlights": ["Promoted to intermediate developer after 6 months", "Accomplishment 2", "Etc."]
      }
    ]
  },
  "samples": [
    {

      "url": "https://rememberpedia.com",
      "date": "2015-07"
    }
  ]
}

And cv2.json

{
  "name": "Jane Q. Fullstacker",
  "meta": {
    "format": "FRESH@0.1.0",
    "version": "0.1.0"
  },
  "info": {

    "characterClass": "Programmer",
    "brief": "This is a more specific cv that should override, or add, specific parts",
    "image": "jane_doe.png",

      "network": "Twitter",
      "user": "janef-was-here",
      "url": "https://twitter.com/janef-was-here"
    }
  ],
  "employment": {
    "history": [
      {
        "employer": "Dunder Mifflin",
        "position": "Intern",
        "summary": "Performed IT administration and deployments for Dunder Mifflin.",
        "start": "2008-06",

        "highlights": ["Supervised roll-out of Dunder Mifflin Infinity website.", "Performed mission-critical system backups and ", "Etc."]
      }
    ]
  },
  "samples": [
    {
      "title": "Asteroids",
      "summary": "A browser-based space shooter built on Three.js.",
      "url": "http://janef.me/asteroids",
      "date": "2014-09"
    }
  ]
}

Both of which validate, and can build the final resumes fine:

hackmyresume VALIDATE cv1.json cv2.json

*** HackMyResume v1.3.1 ***
Validating cv1.json against FRESH schema: VALID!
Validating cv2.json against FRESH schema: VALID!

Yet when you merge them together, they error:

Similar issues occur with JsonResume formats

It is also not very clear what the merging action does.

Does merging override everything defined in the generic json (in this case cv1.json) with anything defined in the specific one (in this case cv2.json). For elements that are arrays, does it merge both arrays or does it overide them? In this example, should the Social fields of the final resume have both Github and Twitter (a merge of both arrays of the json files) or just have Twitter (as it is the only one defined in the more specific cv, cv2.json)

It would be very useful to have some basic example json files as part of the project, I see there are a couple in the test folders but these don't merge either

Using the development branch/release seems to fix this, so closing
