Datahub syntax

A datahub is a JSON file descibing a set of tracks in the browser. A datahub file is an array of tracks, which are also defined in JSON syntax:

[
    {
    "type": "track_type1",
    "name": "track_name1",
    "url": "track_url1",
    "showOnHubLoad": true,
    "options": {
        "color": "red"
        }
    },
    {
    "type": "track_type2",
    "name": "track_name2",
    "url": "track_url2",
    "showOnHubLoad": true,
    "options": {
        "color": "blue"
        }
    }
]

important

For each track in datahub, showOnHubLoad need set to true for the track to be displayed in browser. Tracks without showOnHubLoad set to true won't be displayed in browser but can be added later in track facet table.
