Notes

We are merging contiguous activities of the same type which are very close in time by checking the end time of first activity & start time of the next activity, which is less than a threshold value of 15 minutes.

Sometimes there are activities which are contiguous but there is another activity of type transport in between. For example:

[
    {
        "activity": "walking",
        "group": "walking",
        "manual": false,
        "startTime": "20160209T231816-0500",
        "endTime": "20160209T231833-0500",
        "duration": 17,
        "distance": 12,
        "steps": 25
    },
    {
        "activity": "transport",
        "group": "transport",
        "manual": false,
        "startTime": "20160209T231917-0500",
        "endTime": "20160209T232435-0500",
        "duration": 318,
        "distance": 3390
    },
    {
        "activity": "walking",
        "group": "walking",
        "manual": false,
        "startTime": "20160209T232440-0500",
        "endTime": "20160209T232552-0500",
        "duration": 72,
        "distance": 54,
        "steps": 109
    }
]

The two walking activities are close in time i.e. contiguous but there is a transport activity in between. For these type of cases, we also merging the contiguous activity since transport activities are not being imported.
