Create a JSON DSL for spans

[hantuzun]

Spans are long periods presented in i. column.

Create a DSL for adding spans to the daily planner. If an optional spans.json file exists the planner should be created with these spans.ngles.

An example spans.json file should look like the following:

{ "singles": [], "repeats": []}

An single is an single on a specific time period and has the following properties:

• name
• from: between 6:00 to 23:30, half hours (optional, defaul to day start)
• to: between 6:30 to 24:00, half hours (optional, defaul to day end)
• one of the following:
  • date
  • since and until

A repeat is an recurring time block on the planner and has the following properties::

• name
• from: between 6:00 to 23:30, half hours (optional, defaul to day start)
• to: between 6:30 to 24:00, half hours (optional, defaul to day end)
• days: Days of week array (optional, default is all days)
• since: First day of the repeat (optional, default to the planner's beginning)
• until: Last of the repeat (optional, default to the planner's end)

An example spans.json file is below:

{
    "singles":[
        {
            "name":"Ankara Startup Summit",
            "date":"27 2 2016",
            "from":"10:00",
            "to":"17:00"
        }
    ],
    "repeats":[
        {
            "name":"GYM",
            "from":"18:00",
            "to":"20:00",
            "days":[
                "Monday",
                "Wednesday",
                "Friday"
            ]
        }
    ]
}
