[BenMaruchu]

This is the initial proposed structure for plan

{
    plans: {
        data: [{
            incidentType,
            jurisdictions,
            dates,
            activityCount,
            colorCode,
        }],
        meta: {
            total: 0,
            page: 0,
        },
        selectedPlan: ObjectId,
    },
    activities: {
        data: [{
            description,
            dates,
            stakeholders,
            phase,
            taskCount,
            incidentType
        }],
        phases: {
            // phase name and corresponding activity count
            phaseName: activityCount
        }
        meta: {
            total: 0,
            page: 0,
        },
        selectedActivity: ObjectId,
    },
    tasks: {
        data: [{
            description,
            dates,
            stakeholders,
        }],
        meta: {
            total: 0,
            page: 0
        },
    }
}
