Create record for catalog in data.json

[dafeder]

According to Project Open Data, a data catalog should list itself. See:

http://project-open-data.github.io/catalog/#inclusion-of-the-public-data-listing-as-a-record

The requirements for this are somewhat unclear. POD's example shows the general format to use:

{
    "title": "Data Catalog",
    "description": "Version 1.0", 
    "keyword": ["catalog"], 
    "modified": "2013-05-09",
    "publisher": "US Department of X",
    "contactPoint": "John Doe",
    "mbox": "john.doe@agency.gov",
    "identifier": "1",
    "accessLevel": "public",
    "distribution": [
        {
            "accessURL": "http://agency.gov/data.json",
            "format": "application/json"
        }
    ]  
},

...but the requirements are a bit confusingly documented. We are waiting for a response on project-open-data/project-open-data.github.io#307 to move forward.

Most of the fields in the example are easily generated from existing variables... but where would the contactPoint for the data catalog come from?
